After closer inspection and noticing the valve with the broken pushrod had not
closed, so I pulled the head off to find the same intake valve was stuck open ?
I brought it to the machine shop that done the work last year and he said the
valve was scored and got stuck. He put a new valve that worked fine.I
bolted/torqued the head back in this evening and tomorrow I will put all the
pushrods ,rockers back in there previous slots . then I will bolt/torque the
intake manifold and re- attach all previously disconnected components.And if I
get it to fire up and run healthy I'll be "shouting for Joy" because this was a
pretty big deal for me . you guys are encouraging ! Jimmy C.

I had just about the same thing happen to me. My push rod was just bent, not
broken. The heads needed a servicing, which would have cost about as much as
new heads, so I bought a set of World S/R heads which were only a bit more than
freshening up my old heads. They should be a bit better for performance as
well. If your engine is built up more, there are other heads that might be a
better choice. We left the cam and lifters as they were in good shape still.

I just found the problem .It seems the intake lifter on #7 must have failed
causing the push rod to bend like a slight "S" and break off . so now I'm going
to take the manifold off to retrieve the lifter and bottom piece of the push
rod and look for damage. is there anything else I should do while I have it
apart ie.change all the lifters and pusrods ? Thanks again Guy's, Jimmy C.
