"Old School" Stocker Cams

If the valve spring pressure were reduced, after a period of adjustment there would be no more carnage than allowing roller lifters and it would be a whole lot cheaper for the majority of racers.

I’ve seen roller lifters break and destroy engine parts. Flat tappets are usually pretty reliable. You can run roller lifters in SS. Leave them there. Race a stocker in SS with a roller cam then

And smart engine builders will get 8000+ RPM out of those pressures.
