Re: Replacement heads on Stocker
Hi All,
The reason that most of the replacement heads are only legal in Super Stock is that they have to be modified by filling in the runners to the correct cc's. You can't weld or use epoxy in the runners of a Stock head. Combustion chamber volume can also be adjusted in SS and not Stock. The replacement head just supplies a blank sheet of paper to start with and can be made legal by machining. Whatever you use it must conform to the NHRA Blueprint Specs including valve size. Bob
