This is chasing a problem that most racers are not concerned about. For the old cast iron heads it will be next to impossible to do. For the factory show down cars if one of the racers get a good port, the factory will just have someone make 25 sets with that port and introduce it as a replacement head. Stock eliminator is limited by the cam lift, the manifold, the compression ratio, and the weight of the reciprocating assembly, and most importantly the horsepower rating. As always the folks that work the hardest and spend the most money will run the fastest.
