Default L92 heads

These heads show much promise the guys at LS1tech.com are all over them. I'm thinking of doing an L92/L76 combo at a later date due to some business concerns presently.

Question do you guys know if the headers off of an LS2 will fit? Any and all info will be greatly appriciated, thanks ahead of time car nuts.

They are intended for a 4.065 bore so the valves may be shrouded.

The heads do drop comression some, I believe they have 72cc combustion chambers (LS2 are 67cc I believe) which would make them excellent for forced induction set ups. I plan on milling mine some and porting them especially on the exhaust side. I hope this helps.

ive been following the thread on ls1tech about these heads and i know that you have to have the intake to match the heads because the stock intake wont bolt on . does anyone know if there is still a shortage of these intakes or are they readily available now?

They are becomeing very available. There seems to always be one or two on eBay and I belief gmperformance is now presently offering them. I've inquired and have been told that all of your LS2 parts will work on the L76 intake manifold minus the fuel injectors.
Hope this helps.
