Voxonda:
Problem with topend is the tendency to 'eat' the valve guides. Honda changed the angle of the valves in order to be able to mount these (too) big valves. By doing that they changed the geometry of it with this result. Better is to put some 33.5 mm intakes in the K head and a good portjob and a decent camshaft. Do not go crazy on the cam or take precausion of the valve train.
