Question preload
I have noisy rockers now after my head and cam swap and I think they may be responsible for my average of 5* of knock retard. I have heard different thing about the amount of preload and that each lifter is different. I have the comp OE replacement lifters. How much should I preload them?

If I wanted to be on the safe side would 1/4 turn do? Or would this be too much?
