292H Comp Cam, reusable?? How to tell.

On the guides, it was on the J-heads...... I'm switching to a new set of aluminum heads. Which is a splurge, but I figured rebuilding the heads would be 500-700 and the new AL heads are $1000.

As far as balancing. Yea, they're allot of questions to answer. Its a CAST crank motor for sure. No unusual wear on bearings from what I've seen. No flex plate, so I'm not aware of what was on it, but had factory cast balance I just removed today. I took a picture of the crank what has weld to it that I'm not familiar with, but do have another 73 cast 340 crank to compare to.

Camshaft: I'll get get pics. Cam has some very light surface rust that I think Evapo-rust will cure. I'm just wondering about any funny/unusual wear patterns. I'll clean up and attach pics. Thanks!
