NOS 1938-48 24 Stud Head Gaskets
I will soon be putting my '39 24 stud engine back together with new mains, big ends, rings, cam followers, valves etc.
I have got two pairs of NOS 1938-48 24 stud head gaskets, all still with some of the preserving wax on the metal fire rings. This scrapes off easily with a fingernail. They have the following stamped on them: Ford USA Detroit Gasket Mfg Co Steelbestos 41A-6051 My questions are: Are these a good type of gasket to use? If so, what is the best sealer to use on these asbestos gaskets? 20200726_104918.jpg 20200726_104533.jpg 20200726_104600.jpg 20200726_104546.jpg |

Re: NOS 1938-48 24 Stud Head Gaskets
The gasket you have "would" probably be good....Were it me, a "new" gasket has more "modern" technology built into it SO the ability to perform (in my mind) would also be better IMO the cost is "cheap" insurance. I used a copper coat spray on mine before I put it back together!!! I also anti seized the studs and the tops of the head stud holes to help the next shlepp like me who work on it to hopefully make pulling the heads easier than what I had!!!

I prefer all metal faced gaskets and copper coat on them. You can take the engine apart then. The type of gaskets you have make it difficult to get a head off if it has studs and requires a lot of clean up.

Thanks all for your comments.
I suppose there must have been many thousands of these in service over the years. |

The 41A gasket is the correct gasket for the 81A engine. You will note the small coolant holes are at the front and the rear coolant holes are larger.

Thanks guys. Majority opinion is that they are fit for purpose so I will get coppercoat as suggested by Kube and rockfla and put them into service.
The engine will be loaded up with new parts and I don't plan on taking the heads off again any time soon. |

Later this week, I'll be installing a pair of these on a '40 engine.
