hi I`m new here and have a question about spark plugs,,, i just built my first big block,,its a 454 true 10 1/2 to 1 compression,,, oval port iron heads with bigger rev valves and mild cleanup in the ports,,,they flow the same as edelbrock oval ports,,, 599 lift comp cams solid camand full kit,,, forged crank good rods forged pistons,,, all the safe oiling stuff,,, studded mains all the best gaskets,,, ran 11 30s all last summer without a bunch of timeing (36 total ) no adders i`ve been running 110 octane leaded because i dont want any detonation and the leaded is the freshest gas at our track all summer,,, my plugs have read fine all summer my engine guy has me using ac delco and supplied me with enough for all last season,,, we changed them twice and put roughly 45 runs on the motor my question is what brand and type do most big block guys like to use,,, i want to buy several sets for this season but wanted to get opinions from actual racers and not just the machine shop guy,,, although he seemed to get it right some guys around here say different things
