High Port spark plugs
What are you guys using for plugs on your High Ports. Most guys seem to run NKGs. Looking for some numbers.
If I can cross reference with the Accel plugs which I like a lot I will. Engine is a 11.5 CR pump gas deal. Thanks for any help. |

I don't have a set of high ports to look at but I'm assuming they use what is pretty much the standard aluminum head plug with 3/4" reach plug, 5/8 with a gasket.
NGK for that number in a resistor plug is BKR6E. Go up or down on heat range as you wish, BKR7E etc.... |

11.7 compression 461, this was suggested by Jeff at KRE and the engine shop for my street GTO.
NGK R571A-7 I've run NGK in my Talon and GN and they've always been great.
