The stage V heads are basicly identical to the 906 castings and flow about the same. The advantage with the stage V's is the increased port wall thickness which allows for more agressive porting without risking breaking through to the water passages.

so, same valves size and everything? open chambers etc...

can I use this heads with all my stuff from 452s ? ( rockers, shafts, valves )

what about valve seats and unleaded gas ?

[c00nhunterjoe]

the rockers are the same from 452 to 906, the new heads will come with hardened seats so unleaded is fine

ok I have MAYBE the opportunity to get Stage V heads BUT without valves, and just read the valves are 2.14 and 1.81, so my 452 valves ( 2.08-1.74 ) won't work.

Then also combustion chamber is about the same ( 90 cc ) so would make a milling job to get about 82 cc

I have the porting templates to 452s.

I think I'll stay with my stock 452 and will port. Right now is a headache try to get more parts from USA, and if I have to, will spend on adjustable valvetrain that is more needed instead a heads ( or its parts ) what I have 4 pairs ( plus the ones on my car and 2 NOS there are around on a dealer )

the guy who is telling me about the stage V heads told me they are the regular valve size... and told me the newers are the ones with bigger valves... if so... what I'm winning ? yeah I know they accept more aggresive porting job, but if they flow the same... I DUNNO WHAT TO DO.

Just do your 452's! It will run great and you still have money.
