Need some advice on some extreme clearance issues I'm having with the spark plugs on my GT40s (NOT p's) and the tri-y headers I have on my 5.0 swap '66.
I've already dimpled the living hell out of several tubes but would like to avoid completely crushing the primaries. Anyone used shorty plugs, header wrap or boot insulators?
Thanks
