okay guys the first thread i did its all messed up but lets go back to the question.when you put a cometic head gasket on b16 turbo you have to re-turqe them after a day.A lot of people say that is the way you do it and people dont do it because you dont have to.because before with honda head gasket 175 across and with cometics 150 across and people say that i have to re-turqe my head gasket to get my compression back and also i am using a arp head stud. thanks
