Due to fitting GM Racing valves I have a full set of +1mm stainless steel wasted stem valves for sale, they have done less than 800 miles (2 inlet and 2 exhaust are brand new)
These require the valve seats to be machined, which costs approx £100 at a machine shop.
8 x inlet +1mm wasted stem valves - standard collets and valve guides
8 x exhaust +1mm wasted stem valves - standard collets and valve guides
£125 including delivery
