Short BB Spk Plug Clear Headers, I think.

So, I went on that internet and found people recommending this lawn mower plug for BBs so as to clear headers. Opinions and hell raising comments are welcome:)

My main hope is that it does not disintegrate into the chamber at 5k.

A little history: Jensen Interceptor w/ factory 440 and custom headers which are essentially slightly modified block huggers. We have successfully burned the 90 degree boots off a new set of accel wires then a new set of magnecores. The magnecores had the addition of nice boot sheaths I got from http://cableorganizer.com/insultherm-spark/ and the boots still melted to bejesus and back because the dang boot is completely against the header tubes on like 4 plugs (so the sheath is also mashed to the header). There is no other solution other than removing the headers on both sides and putting a nice massive dimple in there. I am trying the 6 dollar approach first. Each plug was 1.25 from Rock Auto.

I will post after pics of the situlation. Below are a few pics of how close the factory type plugs come to the headers. Which puts the boot directly up against the headers.
