Ok guys let me start by saying I'm totally brand new to the Honda scene. I just recently bought a D15(jdm) block and I chose to go with a Z6 head instead of a Y8. I hear I will have less compression with the Z6, but I also hear it's better for when I boost it... I hear boosting it with the Y8 will be too much compression and It could possibly ruin the engine....did make the right decision?
