Saw a local ad for a pair of 308 swirl port heads, bare castings, checked for cracks. He wants $200 for them. Will they perform any better on my 360 drag motor or should I stick with my 4051's? Motor is a 360 LA.

Chrysler spent a bunch of money producing books for racers. This was covered in the books.
I will say this about swirl. It has been misrepresented. Lied about. Misunderstood. A swirl port head is for emissions. That is ALL they are good for.

Preaching aside - the 308s combine the LA intake port with the Magnum exhaust port. I like to use them, more for that reason than any swirl.
