Taryl said you can run 2 steel push rods if you want. Actually he said he prefers it, won't hurt anything. So the push rods should be interchangeable. Just typing out loud here.Well just a couple thing I notice here that is incorrect.
First that lower rocker and valve is the intake and not the exhaust.
Second you got the push backwards as the aluminum goes on the intake and the steel one on the exhaust. Won't prevent he engine from starting but will cause problems later.
Yes later on someone might get confused in or ex.
