Porting opens up a whole new can of worms.

If you can port, you can cover up almost any amount of welding, within reason. You don't even have to resort to acid, or media blasting, anymore.

Once you get them to allow porting, you'll never get them to go back.

One of my best friends, who is a really good cylinder head guy, said the worst thing they did was to allow porting in Super Stock.

I really can't see where the result will be better in Stock Eliminator.

Of course, the roller rocker rule may be the precursor to porting.

It may accelerate the switch to "aftermarket" aluminum cylinder heads. Because welded iron heads always crack, it's just a matter of when. It's much easier to weld aluminum, and easier to cover it up. The supply of iron heads will dry up even more quickly, and more cylinder head guys will prefer aluminum heads anyway.
