I am running a 426 wedge with factory Cross Ram. Mopar Performance steel replacement heads (MW). 12.2:1, with a large roller cam. .680" or so. I have run Autolite 72's in this car for years. I also run an MSD 6AL with a blaster coil. I typically gap the plugs at .035. I have two questions:

1. Should I run a different plug?

2. Am I gapping them correctly?

Thanks in advance for any help you can give. I'm trying to hit a Test and Tune this weekend for the first time in three years. Can't wait to get the old girl out, but am prepared for issues from sitting.
