When you purchase one of our rebuilt heads, we’ll buy yours back, rebuild it, and return it to our inventory. The buy back value depends on your core’s condition — the buy back value for this listing is shown in the product details. If your core needs repairs beyond a standard valve job, those costs are deducted from the buy back value. If your core can’t be rebuilt, it has no buy back value. •- Cores must be free of cracks, rust, and warpage beyond .003\". Cores missing critical components will not be accepted. •- Your refund is issued after inspection, less the cost of any repairs required — e.g. replacing a burned valve, repairing a dropped seat. Each defect reduces your refund by our actual repair cost. •- Not sure what your core is worth? Send us photos and a description before purchasing — we’re happy to estimate. •- Cores must be returned within 14 days of receiving your product. Late returns incur a $50 fee. ⚠(!) Failure to exchange a core voids the warranty. •- Rejected cores are held at no charge for 7 days after notification. After that, storage fees of $25/day apply. Cores unclaimed beyond 21 days are forfeited in lieu of storage fees. Full terms are provided at time of rejection.

How Every Head Is Built Disassembled > Cleaned > Machined > Repaired > Upgraded > Assembled > Lubricated > Surfaced > Vacuum Tested > Sealed for Shipment Components & Parts We use OEM parts. When unavailable, we substitute new or reliable aftermarket parts: carriers, camshafts, bearings, guides, valves, springs, rockers, shims, seats, freeze plugs. We always install new valve stem seals. All heads are assembled and ready to install. Repairs Included Stripped plug threads, broken mounting bosses, loose freeze plugs, and more — fixed before assembly, not passed on to you. What’s Not Included We don’t sell electrical components — no spark plugs, coils, sensors, VVT solenoids, or timing chains. VVT/VANOS sprockets are not included unless requested at time of purchase. Some applications require additional seals or gaskets available in a top-end gasket set from your supplier. Some heads require a final valve adjustment, priming hydraulic lifters, or setting the timing. A Note on Appearance Remanufactured components may have minor visual imperfections or blemishes. Every head is guaranteed to function normally throughout the warranty period and beyond when properly installed and maintained.
