Little brother got a good deal on heads this past weekend at NorwalkThey

I thought the headers weren’t a great fit with those heads.

I ported a set for an oval track guy who used the “spec” version........ they turned out pretty well.
Basic clean up type porting.

Thought so too regards headers. Buddy has a 70duster. Ran X heads and Hookers. Bolted on the Brodix heads he has now and headers bolted right up. We taked about this very thing at Norwalk( where you need to come... lol) last weekend
