The hydraulic lifters will easily eat up that little difference and your motor will never know it. I would be more concerned with actual valve spring installed height, quality of the valve job and how tight the valve guides are. Really a lot of guys run them OOTB I'm sure.




I agree. My son took his heads out of the box and bolted them on. Ran it 3 years like that before he decided to do some mild porting on them. When we checked them they were good. Ron
