I'm not clear if you guys are talking solid or solid roller
I've used the comp 848 AMC style roller lifter in my hemi and my friends 440.I sent oil up the exhaust only on the hemi and all 16 on the wedge with a 15 lb loss in OP when hot.I had restrictors installed in the hemi pushrods and that brought the OP back to where it was.

HEMI-ITIS has no cure.
My condition is fully BLOWN!!
