Thanks for your help. I figured they were aftermarket. I did/do have the thin steel shims. For those who have not seen it before, here are pictures of Porsche wastegate guts. I measured my valve guide clearance at around 0.3mm.

WASTEGATE BODY & LATER STYLE MUFFLER (note bronze guide)



INTERIOR OF EXHAUST GAS PASSAGE



TOP SIDE & VALVE GUIDE



INVERTED STYLE WASTEGATE VALVE



WASTEGATE VALVE SEAT (This plate fits with a light press to the main body)



CANISTER BOTTOM (note port for boost pressure)



The canister top, diaphragm, and valve retainer are shown above.
