Ofc the traction is my first priority, just curious on what you guys would recommend. if i change my heads this will probably raise my compression to 10.5, this should make pretty much hp though or is the flowing that matters?
Cr matters but you'll gain like 5% so on 400 hp engine thats like 10-20hp so you had air flow gain with it would be good but cr alone not so much for the money.
