Sean:
I have a 1974 Ford 4000, sn is C429995 on a sticker on the inside of the hood. I'm almost positive the engine has been changed, so I won't give the mfg codes. The engine marking is DONN 6015L and a serial number of *D632115*. By your post, the D6 would indicate a 1976 engine. However, it has 1/2-13 head bolts, whereas from what I've gleaned online, the 1/2-13 head bolts were used from 1965-68 and the 1969-?? engines used 9/16" head bolts. Where is the mistake in my thinking? I need to order a head gasket and want to get the correct one. I see two different versions on the web. Did this engine come out of a 4600? Please help. Thank you. Jim
