IH M cylinder head identify

[Dave Panning]

I have a head from a Farmall M tractor. Casting# 70009C1. I think I had one with this casting number on a 450 tractor once. Was this some kind of replacement head? Must not be original. Thanks!

A quick search shows it as a head that would have originally been on a 400 Farmall.

later replacement head, If I remember correct the combustion chamber is like a 400 or 450 gasoline head. Last big tractor show I attended a fellow was trying to sell one as a LP head for big money.
