Its all about bore spacing. Its the reason we can not quite keep up with the Chevy's, Fords and Mopars in the end. No other way around it. Boost helps but NA, forget about it.
They have big blocks, we have a "mid block". Biggest head gasket wins.

I’m not sure that Cheby is doing that much better then us there are just MORE of them! SH_T others had to change the bore spacing on the big blocks to make real hp, once you change the bore space it’s not a Cheby any more. We (Pontiac Racers) are set in our ways and don’t like change. Our block is what it is......10 head bolts, 4.62” bore spacing, HELL people (not racers) are whining about the billet, Warp type heads .....it’s not a Pontiac head even though it bolts to a REAL Pontiac block, now these people (non racers) are whining about changing the bore spacing.....give me a break! We’ll never catch the so called Cheby racers we are out numbered and that ain’t changing! PRTTF! ( Pontiac Racers To The Front)!

GTO George,
How many all out Pontiac have made close to 1200 HP? SBC 4.40" Bore spacing 400 ci almost 1200 Hp or almost 3 HP per ci.

Since air flow does matter to some degree. Just how much do those warps flow? Yes I know this will not get an answer.

Stan

I just used Warps as an example....Dons RA5 heads can go 530, Warps I’m sure are close to that ....what about Jacks billet head?
It’s a money thing most (not all) Pontiac racers are cheap

Air flow is only a 1 part of making 3hp/ci.
