What plugs for ETP heads

Just did some searching on what plugs to use and my head is spinning. I had NGK 7173's on the car and they fouled out very quickly. I put TR6's in and it fired right up and was idling better then before. The car only had some idle time on it and is initial start up but got me wondering. It seems like I have a few choices
NGK 7317, 7173, 3526
AR 3911, 3934
I read about some aftermarket heads being different and the whole tapered seat, gasket seat, projected, non projected thing has me confused.
