Burning tips off plugs

Awesome responses,I like the idea of taking 2 degrees out.
Yes, I went to a colder plug the autolight 3924, great minds think a like.
When rebuilding the engine, I did look to make sure it wasn't burning itself up, nothing else was getting burnt up (melted).
The heads were done by a guy that does most the Nascar heads. They all get shipped to him in Idaho.
Another Mopar race friend mentioned the Vac. leak. I will check, but think it is tight. It's an M1
Headers are not leaking.
The color of the plugs right now are all black from pulling it in and out of the shop. It's so loaded up!It needs a good woopin'!I will check the new ones after a run at our TT in 2 weeks.
It's a drag car, not a street car.
Nothing like experience, and getting help here has that, experience.
Thanks for all the positive info.
