  • Re-conture ports and radius valve seats
  • Re-machine guides and Sunnen hone to fit
  • Finish with SEDRI valve job, fully radiused int. & exaust seats
  • Flowtested on our Superflow 300 flowbench and come with flowchart of your heads (Our heads are tested thru a manifold NOT a velocity stack stuck on the intake port, like some other ported heads. This gives inflated and inaccurate flow #'s)
