Its the rocker studs breaking. Was only 2, both intake. The ideler washes fell off the gear drive or I found 1 in the oil pan but not the oter 1, It was new but did not think to check it for missing parts.Is it to big to fit any where else? the was nothing in the oil, oil pump was not in good shape had some shit go throgh it. Went to a pro gear chain noe for timing,All the push rord are 7/16 and not bent have to chevk the vavles to c if there are bent. I am alittel piss at this motor right now to take the heads off to c the pisston. I just put 15,000 into it. If it runs with out smoking then i will run it. The cam was for drag racing and all the springs are set for the cam, I might have had the rollers up side down(not the flat on top for tighting them down, 1 is tapered and 1 side flat) I did not look when takeing them off untill the last few and there was 2 wroung.
