Hopefully someone can help me out. I have a boat with a 95' 5.0 (302) engine in it. I just got the heads rebuilt and bought new lifters. They are the same diameter and length. The only issue is the the side and top oil holes are smaller than the stock ones (OMC) the engine had. I know boats run at higher rpm's for more time (max 4,200 rpms). Will I have any issue with smaller oil holes through the lifters?
