Farmall A head casting numbers

Stuart · May 31, 2010

I am rebuilding a Farmall A. It is an all original 1940 model with original cast pistons and hardly any ring groove, but one piston is stuck. I know it has the lowest compression head on it. I am going to put the 123 ci sleeves and firecrater pistons in it, and I want to know what the casting numbers of the highest compression head are. I want to put a C or SC head on it. But need the casting number. Thanks for the help

See the link. As for the SC head, I think it has smaller water passages, so it won't work on your A unless you put a water pump on it.

I plan to put a water pump on it, makes it cool alot better and gets rid of hot spots around the sleeves.

I have a Farmall C head, casting number 251172 R2. Professionally rebuilt with new valves, springs, guides and seat inserts. Reasonably priced. If you are going to Red Power, I can bring it there. If interested, send me E mail.
