Troubleshooting Head Components

volaredon said

Id replaced those seals no matter what as a bare minimum as they are cheap, not hard to do, and well, you have the dang head off in your hands.
I rarely pull a head and "not" send it thru a machine shop. I'm not saying I have a competition valve job and full port and polish done, but definitely a basic valve job and check for warp at a minimum. Pretty much automatic.

Kind of my thought on the matter, however, I didn’t know if that would have negative consequences considering I’m not toying with the block/pistons/rings/etc. Curious to know if there is a part number for those seals? I’ve got a parts manual from eBay, but some chunks are missing. I saw on the other forum that parts numbers for a post-‘74 head are listed, but not pre-‘75.
