I just acquired a '37 block, at least that is what the PO says it is and it is a 21 stud. I only got one head with it. Doing the search here, I see that I could block off the lower water outlets and install the '35/'36 lower ports with '35/'36 heads. But, I was wondering, could you like wise run the later style lower pumps and remove the pumps from a '35/'36 head and make new head outlets so the configuration would be like an 8BA? I ask because I have extra '35/'36 heads and maybe it will be tough to find another '37 head.
