The TSP camshaft packages were dyno tested & spintron tested with L99 (heavier) valves to insure valvetrain is exactly what its suppose to be.

For example the 231/236 & 235/239 dyno side by side on the engine dyno!

Thank you that makes me feel a lot better my plan was to go ahead and swap the oil pump and timing chain since I was already there. I honestly didn't want to bother with the lifters yet if I didn't have to.
