Big Block Duster w/2" tube headers: Best solution to avoid burning plugs?

I ran these on my BB Scamp with Herb McCandles headers, They were very close to the plugs and would burn the silcone boots up. Say they are not for electronic ignitions but I ran a MSD 7AL and a Mallory uni-lite with no problems.
