Most of those gap at either .045
But not all. Usually gap them the same as the standard plug. Unless the ignition system is modified.

Vette(s): 69 Conv #'s match 427, TKO-600/.64, 3.36HD-Posi, HT, T/T, PS, PB, PW, SP, Leather, Comp XE264HR & Roller Rockers & Lifters, Air-Gap RPM intake, Holley St Av 770 VS, MSD 6AL+Dist+Blaster SS, K&N, Jet-Hot Hooker Side-Pipes, Steeroids, Al Rad, Spal Fans
I called delco support... dont remember what they told me but it was oddball.. they asked me a few questions and I think he told me something like .038 on my 350 vette
by the way.. let me endorse rapid fire plugs..
I am a huge fan.. they are more expensive but I observed a more complete burn with them... I actually had to crank the timing down a degree to use them... but it ran better than with the timing up and bosch platinums
I think the difference is even more noticable with an MSD or other enhanced ignition.
when my 427 gets back on the road ... it will get rapid fires.
I run them in my 80 chevy truck... the plugs are worth more than the truck.

Thanks,
I'm going through a process of elimination to determine why my car runs rough between 2,000 & 25,000 rpm's. I get some slight popping from the exhaust,otherwise she runs fine. I'm also changing the wires to Taylor Spiral's.
I suspect that the problem will be in the ignition.
