I'm curious about the thread depth for the second spark plug. Many twin plug machining results in no or very slight relief cut in the combustion chamber. Yours seem to have quite a bit. Did you cut to match the length of the plug threads? Also, did you cc the heads and check the comp ratio after the work?
