Not at all, just funny how things can get spun. I'm pretty sure this head will make some strong power. Will it be the best head? Will it be better then other heads that are available. Only time will tell. The only thing we do know for sure is it will be one of the most expensive Pontiac cylinder heads available.

I commend the few that are stepping up to develop this head.

I dont think any one will claim it to be the best head. As far as race heads go, IMO, i think its just another almost for Pontiacs. But i think its a real nice almost. I expect this head to make pretty good HP #s. My HP goal is set and only time will tell.
But you are right the cost, castings are not cheep, will have to be cnc cut, seat registers cut and seats and guides installed. All this adds up. But if they can make the power right out of the gate i think it will be worth it to people. But at the same time i dont think its really any more than a lot of the alternative castings for those that are going after higher HP levels.

IMO where the 11 deg Pro-ports will shine is in efficiency. I really don't think they will make any more PEAK power than a Tiger head but they very well could make more AVERAGE power and torque with over a wider range with a slightly smaller port and shorter valve combo. As Calvin said, they will be pricey but for some applications they might the best choice. Time will tell....

I actually think i could make more power with the Tigers, but i would want to move some things around and do a fair amount of welding on them. I am also not familiar with the material and heat treat like i am with the Edelbrocks. Plus i wanted to be able to make a cnc program for what ever i did to try and maybe recoup some $ on the project, and what i was going to do to the tigers would cost so much for someone else that no one would be interested. The PP is a real nice no fuss deal. JMO

John,

We use the best materials in our heads as well as our Aluminum Blocks. Both are Heat Treaded to T6 temper.

Gabby L. Just did a set of Tgers for a New York Customer. The customer called me with the Dyno information stated he was very please to see 1089 H.P. with no vacuum on a single carb. motor naturaly asperated.

Nothing that I know of was welded or moved around in the head. It was not a all out motor but a bracket motor build.

I hope someone will post the Dyno Sheet soon.

Nice numbers!! Any other details, engine size?

Our Shelf Tiger ,no moving ,welding or relocating is at 465cfm,our Tiger Custom with moving ,welding relocating ,reheatreating is at 490 cfm,136cfm per msca,would need funding to pursue the Pro-Port.Bill C.

Holy crap! That's DAMN impressive!! It usually takes 555"+ of BBC with 12 deg heads to make those kind of numbers.......PONTIACSTTFMF's!!

I agree John about the extensive work and relocation...but that 's just it , the crowd you'd be targeting for a head like that could justify it's price tag being a little hefty...because that's what it takes. Can the Eddy go where the Tiger can go in a high-end application without welding ? in a no-fuss CNC package ? I'm talking sizes to suit an application over 500 c.i. and 2.0 per inch. We do that without welding or relocation so far on the Tiger...the pro-port sounds like a real player as well . Not for the faint of heart cost wise though...expensive head to port and prep...even with CNC packages .

I've never had a call for a set of heads like we're discussing for a Pontiac , not the cookie-cutter CNC stuff... but a maximum effort head...but I have ports and locations...should the need arise . It will be interesting to see how some of this high-end stuff unfolds over the next few months. John

x2!
Good luck with your 11 degree Pro Ports. Looking forward to your results.
