i just bought a 11/69 SCJ 429. i popped the valve cover off to check it out, and this is what i found. does this look like all the factory parts? did the solid lifter cars use a jam nut like this? how about that bottom spring cup?

Looks like a big block Chevrolet rocker arm to me. I could be wrong however, I was under the impression that the Ford "ball fulcrum" rocker arms were cast not stamped, (up until the "sled" type).

That whole spring package looks like it's new aftermarket. And the rockers look like D3 sled style that have been retrofitted to 7/16 stud. I put a jam nut setup like that on a 351M, or 400 years ago to make the valvetrain adjustable. Think it might have been a kit sold by Crane or somebody.

That is 100 percent correct,( EXECPT RETAINER'S) and has an added jam(lock) nut on top, cj and scj use same parts , as well as spring seat cups

the jam nut were sold over the counter because the locking nut( silver) would wear out

the part num not seen on guide plates on early engine is on the under side

No those are drip rails,and are for std heads with the bolt down rockers

scj,and cj have them in the valve covers, as do police
