Wait till you see what I find....

Wow, bud. I haven't seen pushrods bent like that in a while. Did that to my 409 Chevy 20+ years ago.
I would drop those heads off at a machine shop and have them rebuilt with new valves and check the guides. Looks like its burning oil in the pictures. If i recall, your roller cam was only .450ish lift. A lot of bent pushrods for a low lift cam.
