This is the same cylinder head used on our Signature Series Engines. A 3 angle valve job is perfectly machined on our state of the art Rottler seat and guide machine. No doubt about it, these are the absolute best prepared heads in the industry. Fully machined and assembled, ready to bolt on and go. Includes machined valves, hand picked springs, and rocker arms. Valve lift will need to be checked once installed to verify legality and performance. For 2025, our industry leading porting job will be included to optimize the new rules. This is the same head used by the majority of the industry’s leading builders.
