Travis cant answer he is caught in the middle. The 502 rockers are not something new, they have been around for at least 5 years. You cant get the old long slots anymore, people have been refining the slots for years too. Cleaning the slot also cuts down on the breakage and cleaning the oil hole dose too. Clark's rockers address those problems and have been thru tech many times on diff engines both 396 & 427, Arnold Greene also has the same setup.
