first u need to know if the bore size tis the same.... then u got the issue of checking if the pistons have enough clearance with the head... remember even if u start it and doesnt hit, that u got VTEC and the intake valves are going to go lower , meaning that they get closer to the piston.. personally i havent experience that setup.... i cant really remember if they are domed upwards... but if they are,,, i dont think they are going to work... the Z6 piston heads are raelly close to the head chamber... i know since i check that when i rebuilded engine

 

I have heard this set up will bump compression to almost 13:1.
Could that be true?
