This CJX cylinder head has been professionally rebuilt in-house by UNA Performance for reliability, performance and long-term durability.
Rebuild Process Includes:
Fully stripped, cleaned and decoked
Pressure tested and skimmed
Valves cleaned and polished
Valve seats cut
Valves professionally lapped in
Uprated valve stem seals fitted
Supplied With:
Elring head gasket
New head bolts
Matched cam carrier (IMPORTANT: carrier is machined to head and must remain together)
A £100 refund surcharge is available when you return your old CJX cylinder head complete with its original cam carrier.
⚠️ Heads returned without the cam carrier will NOT qualify for the surcharge refund, as the carrier is line-bored and matched to the head.
All returned units will be inspected before any refund is issued. UNA Performance reserves the right to refuse surcharge refunds for damaged, cracked, or heavily worn units.
