After engine reinstall, first start up ends in disaster!

Wow I need to do some research on solids, i allways thought they were something you don't drive on the street and had constant lash problems.

That's likely from problems with stud rockers on chevies. Solid shaft rockers with good pushrods don't have such problems.
Why do you think the HIGH dollar aftermarket chevy heads and rockers are set up for rocker shafts?
