Just for the record, John and I aren't "dealing" with anything, per se.

He was running a combo someone else had come up with, then a change to that combo was made, which exacerbated what I felt was a problem in the original set-up.

As such....... we discussed some options, and in the end went with a new combo........which I'm hoping he'll be pretty happy with.

Fwiw..........on your combo, I would be using different oil(Driven Hot Rod 10w40 synthetic).......... and I'd get the Morel lifters.

Fwiw 2......I have a set of Crane Hyd roller lifters here that were packaged in 2014 that don't look like those.
