Adjustable lifters

[Blowby]

Thanks guys. Gary I assume you drill the holes for and aft to avoid drilling over the intake ports?

With cam on base circle the adjuster bolt is partway in the lifter bore, not sure I will be able to get a wrench on it. I have an old motorcycle with the same situation, which necessitates getting on the lobe for wrench room, then turning it back on the base circle to check clearance. This is a V8-60 if that makes a difference.
