Streetmaster to Airgap

Here's a clue to why he can. There's a reason he can make power with 125 cc. He can make a head flow a lot of air with very little port volume.

It's amazing what happens when you hog out a port, then machine the **** out of the intake side to pull the CCs back down, isn't it? That makes them no longer stock heads, too.

Might as well slap on a set of w2 heads and engrave "302" on them.

Comparing superstock and stock eliminator heads to factory casting is such a dishonest comparison that it renders you nothing more than a troll.
