Sent a note to the shop working on her - should be able to get it posted by tomorrow, thanks!

 

[Nbndallastx]

Actually was just going thru old pics he sent me…is this the casting number? 6105?

3 different cracks on the top end that aren’t repairable

-61050

61050 should be it…..61040 is the rare bird. I think I have one........can check in the AM

 

[Texican]

Is the head off yet?? You need to see if you have flat top pistons or domed......if you have flats, you need the 61040

 

[ERNRAM]

Thats what a 61040 head looks like from the bottom side for your reference.

Close up of the chamber. The purple dye was from the machinist.

Sweet! Just sent ya a DM

He has a 3F. The correct head is a 61050 or a 61060. There are casting differences between early 2F 61040 heads and POST 4/85 2F head. A late 61040 head may work. Dunno.

A 61050 head will work on a late 2F/3F block.

The cylinder head I have is a actual non-US 3F head. It’s been awhile since I had it rebuilt and put it on mothballs but I think it didn’t have air rail ports drilled.

To the right person, those are gold. I had a non-US 61040 head about a decade ago. Got some really good money for it, even then.
