Although the 2.0L bus Type IV is essentially the same engine, it would not be correct to think that "newer 2.0L have hydraulic lifters". No 914 ever came with hydraulic lifters. VW did this only on the 77-79 bus engines.

You can physically interchange the bus type IV with a 914 type IV if you swap the entire thing. Whether a hydraulic lifter engine is a good thing in a 914 is very controversial. Lot's of folks hate them because they have issues at high rpms. I like them in my son's 1975 bus because he isn't mechanical so he doesn't need to do valve adjustments.

I don't know whether the 1.7L sheet metal would work on the bus engine or whether you could use the 1.7L D-jet on a 2.0L engine (I suspect that the FI would not work well and would be too lean), but I do know that the cam profiles are different between the two engines. The bus engine has a torque profile that was made for getting that big box moving from a standing stop. This torque is quite different from what is needed for the much lighter 914. I believe the result is that this bus engine would have issues when you get into higher speeds.
