Rebuilding my bike the threads were destroyed and the lid no longer threads on. I am replacing it. 38pwk or 38pwk AS. The bike will be a BB ESR 350-370 duner any suggestions?

I run a 38 A/S on my 370 ,it does the job ,really snappy on the low end and midrange
I probably could run a 39 or 40 pwk for more topend
But my setup works so far
-
I agree 39-40 PWK for duning

I think 38mm would be BARE minimum for that engine. My stock jug ran a 38 A/S just fine. I'm with these guys. You could use a little larger.
