If I go solid lifter I’d need to use adjustable rockers. At least $300-400 for the cheapest 440 source set I’ve found. I also like the idea of getting the old lifters resurfaced instead of buying new lifters, with all of the cam wipe out stories.
I feel like the best bet to keep from wiping a cam may be to use resurfaced lifters and a reground cam from the 70s.
Also a roller cam seems to come with its own possible issues, not to mention price.
