Well, you read the title. I noticed that the gaskets are different for the two, but I thought they were interchangeable. What am I missing? Thanks.... Oh, yes... I had another similar question. Is the case bore for the cylinders bigger on the 2.0 than the 1.7? I know the heads are different, but I'm not sure about the case. Thanks again.

All stock Type IV cases have the same spigots for the cylinders. The registers in the heads are smaller on the 1.7s, but that's it.
The 1.7 exhaust (also the 1974-only 1.8) is smaller diameter than the 73-74 2.0 exhaust. The muffler ends of the pipes are also a different distance apart. That said, any of the 914-4 exhausts will fit any of the 914-4 motors. --DD |
