Description

SOLD AS A SET   – Price includes shipping to the continental U.S.

NO CORE DEPOSIT OR RETURN REQUIRED

These are Ford OEM re-manufactured cylinder heads, NOT the cheap $325.00 Chinese castings that other companies sell.

O-ringed cylinder heads apply more pressure directly to the head gasket sealant around each cylinder to help prevent future head gasket issues.  We do a special valve job on every O-ringed head which substantially increases airflow, which can lower  Exhaust Gas Temperature and increase both performance and fuel mileage.

Remanufacturing process includes: 

  • Complete disassembly and cleaning of cylinder heads
  • Magnafluxed for cracks
  • Pressure tested
  • resurfaced flat with a finish compatable with OEM style multi-layer head gaskets
  • Multi angle performance valve job with a special cut for increased airflow
  • O-ring grooves machined into deck
  • O-ring wire installed
  • Painted with high temp paint
  • Assembled with OEM valve springs with proper set spring pressure, spring height, stem height and valve recession.
  • Optional high rev valve spring set available for purchase.  (check the box to order)
