"I have often wondeed if mushroom tappets would alleviate some of these problems."
I would go that direction for ALL my engines before any type of big heavy HR lifter set-up, or even a solid roller deal.
A hardened steel cam with hardened billet steel mushroom type tappets would be the best solution to all these problems we are seeing with flat cams "munching" up lobes and lifters these days.........IMHO......
