Z6 to Y8 swap

Z6 to Y8 swap
Allright, I might not be the brightest person out there, but lemme ask this. A Y8 is a better designed head from what I understand, but the compression is higher. If I swap a Y8 instead of my Z6 will I be able to somehow lower the compression back to where it was?

it depends man like if you want lower compression just stick with the z6 i mean its the same thing as the y8 just the y8 is better because it has more compression for all motor requirements. so yes its a good swap if you want to.

a lot of people lower the compression too much for boost. for them, its usually about bragging numbers, not driving. yeah, a T4 might make some nice hp numbers pushing on a built sohc at 8:1, but most of us would hate driving it every day. youre better off with the higher compression and low boost from the smallest turbo you can get that will flow enough for your motor. it will spool fast and still have good top-end power.
