The timing set i have came with the rebuild kit I got from Dave Hyatt about 12 years ago, I did go down and buy a Cloyes brand and the chain and sprockets are the same size. I don't have the old chain or sprockets because they were thrown out years ago when i put my truck into storage. The head i have is definitely a late model, the pic here is of early 22r head with different mounting points for the exhaust manifold.
