I'm ordering new springs, retainers and locks for my early Hemi in the Drag Week hot rod. Looking for 8000 rpm capability. Comp recommends their tool steel retainer over Ti for this application due to durability and they are only a couple grams heavier.

But how about the locks? Steel locks weigh 8.5 grams vs. Ti locks at 4.5 grams for set.

Other than cost, is there any drawback to Ti?

Will 4 grams per valve make a difference?

Thanks,
Joel
