He will have to build his engine to start with, with that lower compression as an objective. He isn't going to be able to have both high and low compression with the same pistons or by swapping heads. Since the 194 head is going to put him over the top, compression wise for his N/A engine, it really isn't an option for him to even consider that head at all. He will have to use some sort of dish pistons, and maybe cut the large chamber head by some amount to get back into the mid 9's with compression. It all depends on what size dish he can find available to start with, and do some number crunching to see if he can find a happy medium to use for both engines.
I realize that this is a bit of a tall order, so I guess the best approach is to build a turbo engine that might have to get by in a N/A state for a while.
I just don't want to build two short blocks, but I need to do something with the current combo.
Using a custom piston is an option for me. I also have no problem having two different cylinder head combinations, one for N/A and one for Turbo.
I already have a Clifford intake and header to use for a N/A engine.
I really do appreciate all of this input, it is opening my eyes to the challenge at hand.
