I have seen alot of posts for the gen 2 plugs to use.....but what would be the best plug for a gen 1, it has the usual add ons exhaust,Roe vec-1, 3.45 gears,slightly worked heads,multi layer steel gaskets, etc. it will be running a 150 nx shot to start....possibly 200 if all goes well.anyone have any part #'s to share, thanks in advance
