What's your choice in spark plugs for the early 351W heads. I'm running a set of 69's on a 302 block and was wondering if anyone else is running anything similar. Right now i'm using accel 0675's but I think I should run something a little colder. Performer rpm cam, long tubes ,2 1/2" dumps,650 DP, 6 1/2 lbs. fuel pressure.
