FLOTEK Performance Cylinder Heads has partnered with JESEL for fitment of most FLOTEK Cylinder Heads. JESEL is a premiere valvetrain parts manufacturer that specializes in rockers, lifters and belt drives.

Additionally, FLOTEK has and will continue to offer heads assembled with quality name brands such as PAC Racing Springs and Manley Springs for added performance.

In collaboration with Jerry Bird/Bird Boyz Racing from Street Outlaws on Discovery Channel, we have developed a larger cubic inch cylinder head. Jerry Bird/Bird Boyz has teamed up with FLOTEK Performance Cylinder Heads for a promotional/marketing campaign beginning April 1, 2019 through next year.
