AS for the lifter bores. Normally, we use Chevy valves when using a cam with more than .350 Lift. This is because you can't get the Johnson extra long lifters. The longer valve stem keeps the adjusting screw tight in the lifter. However, The smaller bass circle put's the lifter down in the bore so it 's difficult to adjust. So we cut the top of the lifter down a bit. as for the cam bearings. Yes alittle more meat in this area will allow it to be bored out for a larger dia cam bearing. This allows for a higher lift valve with out reducing the Base circle. I covered some of this in my book.
