bushing lifter bores on 340

If you use a mechanical lifter don’t drill any holes in the bushings.

If you decide to use a hydraulic lifter (I say don’t do it but it’s your build) then a .040-.060 hole MAX is all you need.

I am using eq heads that'll have magnum oiling system through the push rods does that matter at all compared to the original oiling system that oiled though the heads ?
