OK I have the head info from the previous mentioned motors, plus one loose.
On the 638632 block is head 839680C 3-12 Flat with vlv info
on 636953 we have 640161 4-2 ribbed with vlv info
On the 804380 800376 5-22 and 6-48 with a W4 flat no vlv info
The CJ2A's 641087 has a 800376 under the 6-48 and W$ like the previous one Ribbed no vlv info
and then loose is 637014 W2 4-25 flat no vlv info
Any info on any of these will also be appreciated.

Willys MC/M38 casting # 800376 if the boss at the front is drilled for the water pump bypass hose. If it is not then this becomes a late CJ3A head.
