Re: lifter bore adj hole
Remember................ The lifters were made for stock valves and cam. They work well on cams with up to.350 lift. More lift requires the adjusting screw to cume out of the lifter creating a loose condition and noisy lifters. The easy solution is to use the SBC 1.5 valve which is .060" longer. They also make a larger 1.6 valve winch will allow you to repair a bade seat with out using a seat insert .
