Thanks for the replys. I have plenty of header clearance but i did look at the accell shortys. Im going to give the autolite a try, probably have to order them, checked out a local auto parts store who have ac delco iridiums that are supposed to be high quality as well. Of course I prefer a fellow racers opinion first though.

UR4 V power NGK. Use them on my DART stock replacement Vortecs. Recommended by DART. Burn clean with MSD 6AL and 385 CID 9.2 CR.
