Let's start a new RHS head thread . Pushrods?

Yea, pushrods are going to be last after the new rockers get here. I was just curious, is all.

The issue with the iron rockers (Isky 1.5) is all about the size of the rocker pad and the tip of the stem only being about .020 higher than the retainer. During a sweep of the rocker travel (using .028 lash with the old cam in place) there is only .015 worth of clearance between the edges of the rocker pad and the retainer. Based on the cam that's going to be run, it has .018 lash so there goes any clearance. Comp stainless rockers were shipped today...

But in mocking the motor up using the 7.555" length pushods that were run with the previous X heads, I nearly ran out of thread when trying to get that .028 lash. Then I measured a pushrod tunnel on the OEM X head and the RHS, and what do ya know? It's taller!

Brian, you da man! I always appreciate you edumacting us small block knuckleheads!
