Hi Keith.
She still had the 16valve head when i sold her, no374 i think.
She also had a Janspeed manifold and clubman's mounts along with the 48's and electronic distributer.
The engine was rebuilt by Atkinson's Motorsport in Kendal in the mid 90's and they had to do a lot of work to the head; new valves, seats and a couple of valve guides among other things.
