Shaved E31 Head = 9.5-1 CR
Shaved E31 Head = 9.5-1 CR

Speed RaZer posted a post in a topic in Engine & Drivetrain

I am rebuilding a stock E31 head, and I'm trying to determine how much to shave the head to get around 9.5-1 compression ratio. Also interested in knowing if 280Z intake valves will work with 260Z block, I know the exhaust valves will work. Thanks anyone
