Great on Actuators I replaced mine 200k ago,I dont know about Cam options.
Also your going to need special tool for Piston ring Installation, with new APR ring ontop of liners.
Without tool impossible to install piston ,without Breaking a ring like we did,Oil ring.
Cummins 5299448, with new Monothern pistons on Cummins O/H kit.
New Liners come with Brass shims, I had Cummins come out to check Counterbores just for Insurance All good.
I'll be running Rotella 15w40 with Gear oil permanently.

Are you running the gear lube while breaking in the engine? It's great for a run in engine but may cause those new liners to glaze. Just my theory on the matter, take it with a grain of salt.
