Best Hi-Port porters?
 

Not trying to start a battle or debate, just trying to be pointed in the right direction of the person known to be the most knowledgeable with these heads, it can be hand porting or CNC program?

Thanks in advance and Happy Holidays to all.....:cool:

SD has a good port even though they don't advertise it.

Also Jim Robertson comes to mind.

Second for Jim Robertson. I know he's had at least two sets go through his hands.

Dan Barton has several sets at least he has done.

You prob. seen my flow sheet before but here it is again. For around $3500 back then, it was a good deal.

Dan Barton hands down!

KRE, SDPerf and BES can make them go. I do not have experience with others.

x2, all 3 are very good with that head. Hard to say who is BEST

Tom V.

Not to steal the thread, but Are your heads standard pushrod location?

As far as I know. No shafts either. Harland Sharp rockers and a stud girdle. ... Econo build!

NICE!

I wouldn't even mention the first 2 with BES...

KRE offers a 1075 hp NA option on their site. I'm not aware of SDPerf, BES or yourself offering more?

You know anyone with that engine?
Where did KRE's HP engines qualify in Tom's race at Norwalk?

I do not know anyone with that engine. What I do know is if KRE offers the power level it will deliver, I've been on their pump. Do you offer more power with their parts? I don't know anything about Tom's race.

What I do know KRE is the quickest Pontiac 1/4 mile with Pontiac power. They also have the quickest Pontiac powered door car on the planet.

What is your point?

Gaby did Ryan's Hi ports, BES would be my other thought.
Jim Robertson or Dan are also excellent choices.

Jim Robertson does nice work. See my signature. Keep in mind it's a pump gas street/strip engine with rockers/stud girdles and not a high compression race piece.

What are your performance goals?

Truth!

Why not lay down some criteria first for what the so called BEST is first, are we only going to consider the fastest et and mph per engine cid and car weight?

If you have an 8.50 chassis tag, a set of 370+ HP's, .750 lift cam and a 535 can get you close at about #3000. Easy on springs too. I ran 8.69 @ 159 with very little tuning, chassis or motor. I told SD Dave that I wanted to run 8.80's all day long in the heat and not change springs every year. It runs mid 8.70's to low 8.80's most anywhere. Here's my cam card, to give you an idea.

Agree, what is the criteria to judge by?

Think I'd be looking for someone familiar with the "real estate" though not mandatory if you have the right guy. IMO Its more important that whomever I chose is able to meet the requirements of my build goal.

Generic port that covers a broader range of application or port that best meets the specific build requirement?

Some of you might want to re-read the original post.

Jim

Especially when some don't even have a HP head and 'giving' advice.

:(

2 people in this thread have/run HP heads.
To the op, just do your research, set your goals, see who is running what you want to run or making the hp you want then find out who did their heads.

Hill Performance has done some real nice flowing KRE HP, trend is @ PY.

I have that engine in my car...mine is the original one they advertised @ 1030hp with just the cast Wenzler quad intake. Jeff told me it would go 1075hp with a sheetmetal intake. The motor makes steam. Just everything else in my car needs tweaking. Converter, suspension, ........

Stated- "Think I'd be looking for someone familiar with the "real estate" though not mandatory if you have the right guy."

Agreed, not always mandatory. Nine years ago I bought a very early set of High Port castings and we had a fellow named Rick McConathy do the port work. Rick was well known for his Chevy cylinder heads and was associated with Naiser Racing Components in Houston, Texas at the time. I believe now his business is Slick Rick Racing Heads. These guys were well known and very competitive in Texas Pro Stock Racing circles.

On the first go around the heads were 403 cfm at 0.800" lift, later with additional work 412 at 0.850" on Jeff Naisers flow bench. On my engine builders bench they went 417 cfm at 0.850" lift. Later with these cylinder heads our 930 hp 526 cid Pontiac engine was pretty good stuff, today it's no big deal. Same with the heads.

FWIW Dan Barton is at Naiser now doing their heads now.

I guess dynos don't count?

Come on man. Where are you at NA? Or on the juice? Your engine has been on the pump. Where are you at in the "truth" position? KRE offers off the shelf a 1075 hp NA engine with cast High Ports and a cast manifold. You and Gaby must have delivered more with the billet head, DRCE, bad arse, best of the best, canted valve racing engine. Since you know, you must have delivered significantly more power. Where's it at man? Dyno sheet please.

you not having a mr1 never stopped you from shameless plugs and giving advise.....just sayin.

et and weight on your ride?

All i have to say about KRE's 1075hp is LMFAO! Just because a piece of paper says it makes 1075 doesn't make it true.

:pound::pound::pound:

Think you know everything I guess?

FYI, there's a MR-1 block and a HP heads in my dragster out in the garage.

:)

oh my god...Did you finally "EARN" your block?

Best porter for what application? There are to many variables in this. If you wanted every last bit they could possibly give you the bill will be huge. Not to mention the valvetrain expense (like previously mentioned) it would require to make power with them. Everyone has a budget (some larger than others) that they have to stay within. Its not that hard to figure out how much airflow you need to make X horsepower at X cubic inches. You may not need as much flow as you think.

Forgive me for being a bit vague, but I grudge race my car and don't go into great details with it on public forums, but in its current configuration it's a Stock block with a standard degree head, cast intake, one carb on motor! But I feel it's time to step this program up, because the stock block can't take much more of this, and I'll need more head to support the next short Block! Just wanted to know who has dedicated the most time successfully with this particular casting, I have a goal in mind, and would discuss that with the porter in question.;)

I was following his progress, but I have not heard any updates for quite some time, I even bumped his topic up a couple of times for further feed back.....:oogle:

I know there's only a few sets of his HP CNC heads out there but I'd say the best thing to do is give Calvin a call. I'm sure he would be more than happy to answer any questions you have.

Dan Barton has been working on my HP heads since 2009-2010. He'll get you to your goal guaranteed, Gaby or BES are also good options.

IMO. Any of the cookie cutter CNC versions from various vendors would get you into the 850-950hp range. Beyond that it will probably narrow the field down and drive the price up.

5.40@129 w only a 1.28 60
2900lbs
Like I said. Power is there. Everything else with the combo is a bit off.

I've got a set of Dan's worked over HPs to go on the 500 if the E heads on it don't get me the et I want. He freshened and twesked the KRE hand ported E heads that are on it.

Saw Slowbird's stuff when I have been there before too. A few other guys from here's stuff also over the years. He did my 409 heads also.

You run the 1/4?

Agreed. So have you been on their pump to compare?

^^^^ This in spades, well done Tom^^^^

Some facts for you,
Car #1 dynos around 1030hp runs 5.4@129 weighs 2900lbs, has ladder bars, tunnel ram and 2 carbs
Car #2 dynos around 1030hp runs 5.43@128 weighs 3300lbs, stock suspension, victor intake and 1 carb
What conclusion do you draw?
Can you show me a 1000+hp kre that shows it on the track?

I don't understand this post.

These cars could be running 5.30 @ 130 or there abouts. Clearly the delta can be found in the chassis, tune etc.
