Best Head Gasket for an Allis B or C

Greetings,

Last summer I had to do some head work on my 1940 Allis C. Right from the get go the head gasket had trouble seating. It was a Mahle gasket set, with the modern dark gray fibrous material. After several re-torquing of the head bolts, it seemed to stop. Well, now if find I have coolant in the oil and oil in the coolant. Also, #1 cylinder is getting oil in it.

The engine starts and runs great. Purrs, had lots of power, etc.

Before I take it apart, I wanted to see what recommendations you have for head gaskets and how to install them. I am toying with the idea of pulling the sleeves and replacing the oil rings just in case that is an issue.

What say you? Any help would be appreciated.
 
I seldom bought a gasket set and ordered head gaskets from Sandy Lake Implement. I have never had a problem. They were the fiber type. I would check the core plugs under the rocker arms as well as removing the pan and placing a cardboard under the block. Make sure the radiator is full and watch for drips of coolant before removing the sleeves. If the O rings on the sleeves are leaking the cardboard will pin point where the leak coming from. You will want to wipe the oil out from the bottom of the block to keep the cardboard from getting oil soaked and hide the coolant drips if there happens to be some.
