What is the stock lifter preload range?

I've seen on this site the stock-lifter preload range being referred to as acceptable between .030"-.060", and also .050"-.100". Which is it?

OK...Thanks!

Which would you opt for - a preload of .060", .080", or .105" ? (stock rockers, stock lifters)

Using a combination of pushrods (I have 7.350", 7.375", and 7.40") and .010" rocker shims, I can obtain any of those preloads above. Any benefit of one over the other?

TIA!

I like mine at around .080.
It leave a little room to breath (upon high rpm pump up) and it is still quiet enough.

What size pushrod would give a .080 preload with a Comp 230/232 .592/.595 113 XE-R cam with stock heads and lifters. I have 7.425's
Thanks
