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.
