I was wondering if anyone over here would happen to know how much lift you can do on an LQ4 untill you need to put valve reliefs on the pistons? Cam Im looking to go with is .635 lift and the previous owner had reliefs on his pistons just incase. Motor is an LQ4 with stock crank and 241 heads. Thanks guys, everyone on PTnet said measure it but I was hoping someone would know
