Re: aluminum heads
Well, thay only made that engine one and a half years 37 and early 38, late 39 came out with the 24 stud. I know 37 had both aluminum and cast iron heads, I don't know about the early 38 but I wouldn't doubt thay have both. Walt

Re: aluminum heads
I believe thay would because people have used the 32-36 water pumps in the heads on the 37 engine and block off the front water pump holes. BUT, if you use the 37 heads on an earlier 32-36 block, what are you going to use for water pumps? Walt

The al heads were discontinued mid feb 1937, so they only lasted for the first months of production of the -37. Lennart, Sweden |
