Specialist Components Super Sport stage 3++ cylinder head has been developed as the ultimate fast road cylinder head for the classic Mini. Comparison to similar named products less expensive or more expensive heads is irrelevant, this is the best 5 port cylinder head on the market in terms of hardware and porting expertise. We tailor these heads to suit the engine they are being used on - we don't offer anything less than the best to suit your requirements. If its a race head it will incur more cost due to the time involved in porting to that level, as an idea a 6mm stem valved race head would be circa £1600.

Lead-free exhaust seat inserts are fitted and multi angle cut. High quality bronze guides are used along with the latest specification single piece stainless steel valves (35.7mm inlet and 31mm exhaust) with race double valve springs allowing up to 515 thou of valve lift. valve spring heights are set and the head assembled with brand new EN24T top caps and race spec collets, viton stem seals across all valves.
