Exhaust Valves for 3.6L M64/01

[Old ITW]

I have everything except exhaust valves for a complete head rebuild. Pelican Parts shows the OEM Porsche exhaust valves ($180.50 each) and TRW exhaust valves ($28.50 each) as available.

Does anyone have an opinion on the TRW valves and/or is anyone aware of an alternate supplier with good quality exhaust valves?

I used TRW valves in my 930 build, good valves.

The Porsche ones may well be TRW. Sometimes Porsche culls through and picks the best ones to sell. I've heard that's the case with engine bearings, for example. Or they're just marked up. Perhaps someone here will know more specifically for valves.
