All the stainless steel block-offs always burn thru, not sure how a plug would fair. It would be better, last longer, but how much longer is the question.
There is a slight performance aspect to the crossover, tho not sure how much of a benefit there is. I suspect 'conventional' methods to provide the same benefits would be just as effective, possibly more so. I used to block them off but gave up. It's just not a priority IMO. EDIT: My understanding is that the best way to block the crossover on OE heads is to fill them, then grind them smooth and to shape. .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
