The heads are made from A356 aluminum castings that are heat-treated to T-6 specifications. Features include larger-than-stock intake and exhaust ports for improved engine efficiency. The heads also have hardened spring cups, as well as the company’s Heli-Coil threaded inserts for exhaust flanges, to help to protect against long-term wear.
The E-210 Cylinder Heads feature 3/8-inch rocker studs. Two different valve spring options are available to accomodate a variety of camshafts.
The heads’ combustion chambers measure 64cc and the intake runners and exhaust ports have been revised for increased airflow, while maintaining full compatibility with off-the-shelf headers and hardware, said the company.
Additional qualities include manganese bronze valve guides and stainless steel valves with hardened tips. The heads are available bare; complete with springs that support up to 0.575-inch lift; or complete with springs that support up to 0.650-inch lift.
