i replaced the plugs with a/c's when i bought the car but now im reading here and there about gaps, heat range etc. i need suggestions (and reasons for em) for my 307,w/edelbrock performace pkg. i used hotter plugs (why i don't know, just sounded cool in the parts store i guess) and i have an HEI set up. i need some good suggestions for plugs and gap ranges to get this thing to run Topps.
