Good Plugs & Gapping for my 6037's??
 

I'm almost done my head install but I need advice on which plugs and gapping works best on my 91GT with my new 6037's I also run Mac 1 5/8 shorties. I'm not running any power adders. Suggestions??? I don't want to run the Champions Edelbrock suggests or anything platinum or splitfires etc.

I've got AC Delco R44XLS in my 6032s right now and they've been the best so far. (2 sets of Champions RN12YC, 1 set of Autolites, all of which royally sucked) Motorcraft AGS32C are also good ones to run. If you have an aftermarket ignition, go with the specs on that (usually 0.050"), other start with 0.040" and go from there.

motorcraft AGSP32C. if you want a colder plug, run 22C.

also , the correct style autolight plug for th edel head is the 39XX series.
