Cylinder Head services
Our stage 3 Mini cylinder head has earned us an enviable reputation in the high-performance sector. This head is totally performance ready with gas flowed, engineered combustion chambers, polished, ported and flow tested with uprated hardened inlet and with exhaust valves guides and seats fitted.
But our cylinder head services don’t stop with Mini. Here at Fiennes Performance we can undertake porting, polishing, combustion chamber modifications, valve guide and seat replacements, 3 angle valve seats and vacuum and flow testing on a wide range or cylinder heads. We can also carry out specialist welding to repair, restore or modify if required.
Our reputation as specialists in air- and water-cooled Porsche engines is unsurpassed in the UK performance market.
