30mm (+2mm) stainless steel exhaust valves with matching cotters

I bought the whole lot from Burton Power for £140 in January

Burton said you can retain all the standard parts in the head and a straight swap, the head just needs a bit of machining which I have been quoted from £80 up to £110 for, including the fitting of the valves.

Everything is still in its packaging so I would like £130 including p&p

In the pic is one on display with the cotters, all the rest are sealed

 

will fit all silvertop and blacktop engines.

ideal for turbo setups where you lose some volumatric flow capacity by running a turbo cam
