cevtv-wow. That's a lot of gap for stock. Can't imagine it would cause a problem. If anything it would run worse with less gap on a stock system? Mine must be more than that then. I haven't done plugs in awhile. I know it's about .008 or .010 over stock for me. Thanks!
Depends on the intake. The stock heads are the choke point. I replaced the heads first, and put the stock induction components on top of them until I could afford to replace the stuff up top. If you can't swing the cost of the heads, then get what you can and you can bolt it up but you will probably not see dramatic improvments. And should not hurt anything. Once I got the intake, MAF and TB, my heads really wake up at 3k rpm. Faster than a speeding armadillo...
Found it. 10 min to find the web site, 10 min to sift through all the BS. so mine must be set at .060 than if thats what the instructions said. Not sure where they got the .015-.020 larger than stock numbers from if stock is .054.
Regap your factory recommended spark plugs to .060 (this is larger than stock by 0.015 to 0.020inches).
