Used OEM bare head for 97 to 01 Honda Prelude with P13 PDE HF-1 stamp. It came off a 01 Honda Prelude, a good running engine with no mechanical issues. This is a bare head,it comes with exactly what you see: cylinder head, cam caps, and lost motion assembly. It has been inspected to make sure nothing is wrong with it. Valvetrain was removed as it was intended for a port job.
