Burned pushrod

I primed motor when I installed the restricters, can't cut valve covers spark plugs are in them, the restricters are on the intake rocker shaft the oil passage splits when it goes into the rocker shaft support one to the intake and one to the exhaust rocker shaft. I'm thinking I will try a new rocker arm, running out of spare exhaust pushrods. Thanks for the ideas, still got a few months before good weather.
