Description

Price - £735.00 + VAT

Now only applied to customer supplied casting. It is now often cheaper to have head castings collected by my carriers from overseas customers and brought back to me. 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!

Inlet valves: Genuine REC 33.27mm, single groove collet EN214N plasma-nitrided
Exhaust valves: CST 27.18mm, single groove collet EN214N plasma-nitrided

Based on used core 12G295 original Cooper spec castings, it is modified to current road-sports style to maximise road-sports and track day/weekend-warrior performance when used with road-sports and super-sports camshaft specifications. The larger REC inlet valve is used to achieve a well-performing valve seat/throat area. The 295 is notorious for having very narrow inlet valve seats as standard leaving no material to work with to improve flow.

Fitted with exhaust seat inserts for unleaded fuel compatibility.

All cylinder heads are done to order as I have always more heads on order than I can ever hope to catch up with to produce stock for the shelf.
