Hey Dick - I am no good at the photo sharing thing, but no big deal about the later block. Cam bearings are a good thing, and with a low port head and H4 carbs, your engine will be absolutely period correct. I am in the same place with my TR2, as the original block just couldn’t be economically salvaged, and it is now garden art. But I have the right head and carbs so it’s all good.
