Glen, thank for your response and your welcoming.
First, the rods were not bent. They, approx. 1/3, had wear on their tops. Cam looked fine as did the lifters. One was much worse than the others and was probably the one I could hear ticking. The carb was leaking from the acc pumps and just needed a rebuild. I've read about using the oil additives and heard some horror stories about not using it. So have already bought some.
My pistons are stock, the head gaskets were from edelbrock. Heads are only a year or two old with maybe 2,000 miles on them. I don't think the studs have backed out but will check that. Rockers were the original ones that came on the engine.
Just trying to figure out what happened and prevent it from happening again. Also wondering if roller rockers are worth the money?
