Should only be 1/2 turn from zero lash. Might have a couple of bum lifters.



i agree. modern lifters are supposed to be 1/2 turn, not 1 1/2. check the docs for comp cams or something, or if you know the manufacturer of the lifters. there are only a few companies making lifters these days that are bought by most cam companies, so it should all be the same.
