So Harland Sharp made a .070 longer rocker for me and now it is dead on.

Just making sure you checked geometry using a solid lifter with the same overall base-to-plunger height as a pre-loaded hydraulic lifter.

Hi mike

I had the hydraulic lifter pumped up with oil as well as using a check spring. So the lifter never collapsed when I checked the geometry. After sometime driving the truck I'll pull some rockers and see how everything is wearing. But I feel confident with how I set up the geometry.

Thanks for your reply.
