There is some false info about the regular de valve covers not fitting... they do fit.
This is true. At least I can confirm that basically everything from the top exterior a low port engine will swap over. Intake manifold, exhaust manifold, valve cover, water piping, engine brackets, mounts and brackets, carrier bearing, belt driven accessories. You can even retain the RR oil filter housing but its a very tight fit the filter against the power steering line. Not sure about the oil pan.
In case anybody needs to know you can fit old style mounts, manual shaft, neutral safety switch, and interior electronics from an old (1993) automatic tranny to a RR-gen automatic tranny as I put a 2001 A/T into a 93 G20. You have to use the old neutral safety switch for the old car which requires the valve body to come out and the manual shaft to change over
