I would hit the 11.5 compression target and run Avgas as it is cheap and works.

The SD ported 272 cfm #48s, 70cc heads I sold might get you close. I believe the fella I sold them to might be interested in selling them. As far as I know they are still new as SD shipped them to me.
Probably get them for around 2K. They were very nice heads, wish I did not sell them.

I plan to contact Dave, he's built a couple sets of KRE's for me, I'll see what he has to say about building some D port Iron heads specific for my application.

The prices I've been getting behind the scenes for 614's and 722's is just ridiculous considering I only need cores, they'd be built specific anyway. I can't put 3 grand into a set of cores and start from there.

I did talk to a couple of our "head" players about building IV's in Iron since prices are getting close to where Iron V's were only a few years ago, but they don't think there is a market for Iron IV heads.
Which I don't understand, if I could buy built new Iron IV's for 3 grand I'd do it, but I can't put 3 grand into 50 year old IV cores and then another 3 grand into the build. Yet people will drop 3 grand to have old D ports ported and built.

You are looking for castings that belong on cars that bring North of 100k. The original service heads bring big money especially when they have never been touched with a grinder. But all RAIV heads have always been desirable, brought good money and are still IMO one of the coolest heads you can run on a Pontiac. The last pair I've seen go for less than 2k was a couple of years ago and they had several cracks and a boogered up port job.

I think you can reach your goal with either head but it will be considerably easier with the round ports and they will be more reliable. The d-ports will have to flow at least 260 cfm but need a maxed out exhaust port to make good power at 7k on a 4" stroke engine (I hope that's what you are using). I'm not sure how the thin ports will hold up under road race conditions. Not uncommon for them to start leaking water after a lot of 1/4 mile passes.

Years ago one of the reproduction parts companies were going to make the RAIV heads but unfortunately the "made in the USA" company they hired decided it was easier to steal the front money and spend years in court than get off their azzes and produce the parts they were hired to make.

I think you can have him set up a pair of your cores for around 1800$. Not too bad really. I have another set of 48s I might have him do.
Butler was hooked up with someone years ago that was supposed to reproduce RAIVs that went 290cfm as cast. Myself, I would like to see some 614s cast in steel. Then you could easily "wide port" them and have something special. Do them with modern chamber and plug placement, killer head IMO.
Stock looking street racers could make some money with them . As far as weight, its not like you are taking 100lbs off your engine like a BBC going from iron to aluminum.

I have kicked myself in the @$$ for not buying some 614s when I had the chance. Way back when I started my 455 build(85) I bought 197 HO heads for 600$, good deal. But I could have had 614 RAIVs for 900$ untouched from a guy Dan knew. I cheaped out. Ended up with nice heads but would rather have the smaller chamber RAIVs.

Can the OP run E85 fuel?

In 1988-9 I paid $1800 for bare new SR 614s.

Edelbrock dressed Pontiac head 36LBS, Iron D ports fully dressed 62lbs.

Anyone built anything similar?

1. 1969 #722 Trans Am heads, Ready to go w 0.550” lift roller cam comparable.
2. OEM “Winters” aluminum intake.
3. Round port OEM Cast iron Trans am F-body Exh manifolds.
Rare pieces in good ready to use .
$8K firm!!
I’m not actually all excited / interested in the departure 0f these rare components yet will On this one offering here.

[R 70 Judge]

Just build a Ram Air V. You'll hit 600hp and 7,000 rpm pretty easy. Seems like its damn near the same money at this point. Tom S has a set of RAV heads for sale now. Just need to find an intake

[pontiacmark]

Regarding the E85, question, wouldn’t the efficiency loss be a problem.for fuel cell capacity for hour long road racing?

[tom s]

No TQ coming off the corner IMO with Vs.Tom

[tom s]

McCarty intake makes a good race intake and are cheap.Tom

[tom s]

Oh,it's a single plane.Stock not so cheap and impossible to find.Tom

Tom, now that they'll allow a 428 in a FGF you have no idea how bad I'd like to build a dual plane "428" V for road racing. Just gotta match those lotto numbers.
Basically my dream engine.

[70pontiaction]

But, really, it AIN'T gonna happen. Not any more.

It's just reality - they're worth $3k if you actually need them.

Which is why I think there's a market for new Iron replacements. But the guys making them say they're isn't so there's only highly desirable, expensive originals.
I've given up looking for now and am pursuing a set of build D's. I can't spend 3K on west coast cores, pay shipping and hope, they'd need a certification from a shop that they're not butchered up or cracked, so far I haven't found anyone willing to do that. It's buyer beware. If I find some within driving distance I'll check them out.

I'll end with this though; so long as replacement parts like blocks and heads become unavailable or unaffordable, the classic Pontiac engine will keep getting replaced with chevy's or LS's. I have no issue using aftermarket parts, but not everything needs to be aluminum or race ready. I like our options but there's not enough of them. Most everything is race.

I have said it before, a new RAIV head that flows like a E head, room to port, modern chamber that looked just like a stock head would be a big seller.
And make it in cast steel, easily welded so you could wide port them for the ultimate sleeper. Guys could make some money on the street with them too.
If you have to cast it in China to get it done, so be it. Not want I want but do not want to see Pontiac shrivel on the vine with the dreaded LS taking over in our cool old cars either.

[tom s]

NO pontiac head is a "BIG" seller when looking at ROI!Tom

[Skip Fix]

Tom I was shocked Edelbrock came out with so many 348-409 parts looking at ROI a smaller market than Pontiacs!
