It is upsetting how well the stand GM LS series heads flow,
an luckily for them ( for now) we dont have a 360 off the shelf
head that flows as well an is affordable as theres.
Do these heads accept 350 chevy rockers, valves, pushrods[stock 350 length], intakes,and springs?
The ports...are they in stock location? or raised?
LS7 don't work on a 4'' bore due to the giant 2.20 intake valves.
Oh wait the L92 use 2.16!!! intake valves
And looks like you'll need a new spring and retainer kit cause the L92 comes with wimpy stock lift springs.
