These are brand new, blank OEM EJ257 B25/V25 Heads straight from Subaru.

Repairing an engine failure? Building an engine from scratch with your own internals and valvetrain? This is a great option for you, since Subaru no longer offers fully assembled heads as a single part number.

These do not contain valves, retainers, springs, cams, seals, gaskets, etc. This is just the blank head casings as pictured.

If you need to verify fitment for your application, or have questions about your engine build, please give us a call at 303.402.5142!
