What is weight break and what class/type of car is this? Wegner Automotive Research in Markesan, WI would be my go to for something like that. Very talented and racer friendly shop.

If you can't run a roller I assume you cannot run Ti valves?

I agree on your choice of rocker arms. Failures occur on an endurance engine that you will never see on a drag engine.

They use several different engine packages.

I'm running the IMCA modified engine pkg in a dirt late model. Iron block and heads, flat tappet cam...not much else for restrictions. Get a 50# weight break. Not much but it is something.

My engine was in mod thats why I'm using that engine package.

The competition use everything from a 360" spec package to 410" unlimited iron block engines making 850-900HP. The big horses rule. I' m there to compete as best I can before I become worm food.
