My experience from about 2 years ago
I have a comp xe 268 in a 340
The comp lifters that came with the cam would bleed down right after running then clatter next start until they pumped up.
Called comp to ask about that,
The guy said so what why do you care?
Well after that conversation I called Lunati
He said their lifters are made by the same manufacturer comp uses and probably would not be any better.
He recommended Johnson or hylift Johnson lifters. ( two different companies. )
I had a new / old mopar purple shaft kit from 1990
I used the lifters from that kit no more problems!
My next cam will be a Lunati because of their honesty not just selling me lifters that probably wouldn't be any different.
Hughes sells hylift Johnson lifters
My 2cents...
