It’s almost 2025 & we’re dealing with either paying stupid money for lifters, guessing from a large manufacturer or worrying about flat lobes, no wonder guys switch to LS motors, what a sad state of affairs for us as Pontiac lovers.

Most problems on this have arose from engines that use HR cams to get a lot more power. Pick a small mild profile, .5” ish lift, with a cam intensity of 54* or more from .006” to .050”, don’t use to heavy of springs, and you will more than likely never be into your engine to look a the cam again, even with cheaper Morel or comp lifters.
