Description
CST2003 – Cylinder head, full race large-bore
Price - £1595.00 + VAT.
Surcharge for head casting if not supplied - £225.00 + VAT. I now urge all UK based customers to try and source/supply their own castings as buying used core in reasonable quantities with the majority in usable condition is becoming very rare. And it is now often cheaper to have head castings collected by my carriers from overseas customers and brought back to me than pay the surcharge. Ask me for a cost guesstimate. I can offer the collection service to UK customers as well to save them the hassle of sorting a courier company. Often cheaper too!

Constant research and development over the decades using a flow bench for initial investigations, then thoroughly tested on engines on engine dynos, rolling roads, and ultimately the race track has culminated in the current race head specification. Instantly recognisable from many other race head types by the distinctive port shapes and sizes. Particularly the valve sizes used and the exhaust ports.
Fitted with top quality unleaded fuel compatible exhaust valve seat inserts.
All heads are done to order to cater for specific applications and requirements, hence the valve size option. The larger valve size may also be fitted if the head casting being used has particulary damaged inlet valve seats.
