There is a chance, just a chance, that 905574 is the part number for the cylinder head. Willys part numbers tended to be 6-digit numbers - for example the cylinder head for the L-134 was 640161.

But - it could also be just a casting number ...

The parts book for a year using the 6-226 engine would tell you if that is the Willys P/N.
