My last set of Speedmaster heads for my customers till late Fall

Awesome job John. What do they flow? Kim


Not that far yet but with a more “street friendly” valve job and a 2.055 valve I’m guessing around 308 [email protected]. Going to the pistol range tomorrow for awhile but this head should be done tomorrow night as far as port work. Then I’ll hop on the other head so both are ready for a valve job together.
