I have a random spare 2f head but no clue if it’s domed or flat piston style. I can check if you’d like - @WhiteTiger911
Yeah that would be great whenever you get a chance.
I want to say there's a serial number on the head that will tell you what year range it came from. If not, then combusion chamber picture will help get us close.
Mines a 61040 from what I understand that’s for the later 2f with flat top pistons, the 61030 is dome top. Not 100% just from what I’ve read so far that seems to be the case.
