This is an old thread, but I'm searching for info to educate myself on flatheads. In post #5 above there's a photo of a 21 stud engine with water pumps in the heads. Someone later said it was a '37 engine, but I thought that '37 engines had water pumps in the block, and sometime, if it was a late 21 stud (replacement block) it might have Ford-installed block off plates in the block, but might still retain the pump-in-heads configuration.

Please correct me if I'm wrong, or I'd be happier yet to have someone verify that I'm thinking on the right track.

Thanks
