Yes! What he said!Use a lifter that fits the bore. I see to many under size lifters, Last Ford block that customer had Comps and they were .873 and need to bush the block to get the clearance correct.
I am partial to the Morel lifter they seem to bed to the OEM spec as far as size.
Im on my 3rd season on them with no issues. I like them but have heard negative stuff about them too. Morel is probably the best lifter, I will try them next time.I put in Crower EnduraMax .904 in my BBC and I bushed the block. I have very few miles on it, but so far no problem
I have used comp endurex lifters years ago in a race only application. 300 seat 850 open spring psi. Didnt last a season without breaking. Broke 2 one season. Stay away from cheap chinese built lifters.
