Jon, how well whould our A heads work on a 604? At what point should we look at a different head?

With a 600 inch engine, I would say one can come awful close to those 1,000 horsepower numbers with using Kaase's P-51 heads ... over 1,100 HP with the "A" heads, for sure.

IF I RECALL CORRECTLY WE MADE 1039HP WITH A 572 A-HEADED MOTOR BACK IN LIKE 1993-94 SOMEWHERE AROUND THERE WITH 1 CARB AND A CAST MANIFOLD ON KAASE'S DYNO. I REMEMBER ON THE FIRST GO AROUND WE HAD SOME BAD LUCK A MALLORY WEIGHT FLEW OFF THE CRANK WHILE DYNOING. WAS PROBABLY THE ONLY PART ON THE MOTOR THAT JON DIDN'T TOUCH. HE REALLY TOOK CARE OF US AND FIXED IT ALL UP.
