I am going to be using the stock head for now... while I am building the performance one... it is fully ported, intake bosses removed, 1.94 1.60 valves, undecided on the lump.
C/R is going to be 8-8.5:1... depending on the pistons I can find. I still have not found the forged pistons.
Boost is going to start at 5.5psi while the engine is breaking in. Then it is going to be 10psi!
