I'll chime in again, I'm toying with the idea of not running the tiebars. I can remove the holders and turn around the lifters and use a bar...Actually 2 bars split in the middle. We always used aluminum bar stock about 1/4" thick and 1/2" wide. We "notched" it for each of the push rods and never had a problem. It's mounted on the outside and clears the side plate without problems. They are held down with 2 10-24 machine screws.
I need to look at the Crowers to see if it will work; always did with the Herberts. Still running a flat tappet since I rarely see 6000 RPM. With my home made rockers I have .615" lift on a cam ground from a stock steel GMC. Good Luck
