But good luck with that!

Maybe he was trying to hold the valves open to bleed off compression to combat detonation.... :P

for any hydrolic lifter to function properly they need .040 preload on plunger. that is where 1/2 to 3/4 turn comes in to play.

if it's stock it will work.or on a small block.just ask a big block company.or ect.like brodix,or dart(there also small block)or some big machine shops.on a big block the lifters build up more when you rev them up,so if there 1/4 or 1/2 turn it will be like 1 1/2 or something when racing.also roller rockers and poly locks or hex locks are important.
