AFR Blue Hornet Mopar cylinder head, Charles Servedio

I can tell you the SM casting can take a lot of porting! When Bryce was doing his airwolf heads, SM added more material to the casting (so he told me). His program was a little thin under the spring seat area, but overall those heads held up pretty well in running engines.

I'm getting ready to do a set for a customer, so I guess we'll see.

Those heads Bryce did were on a buddy’s car. Same guy I mentioned in another thread. Local friend.
He took those heads off, swapped on trick flows, and the car( Duster) ET’ed almost identically.
Stroker, Hughes 264/268 solid Hustler headers, etc. been racing for a long time. They ran a W8 deal for a number of years.
At this point, they had kinda thrown in the towel on going faster with what they had.
I talked them into one more effort, they are glad they did.
