175 valve sizes
Posted: Sat Jul 11, 2026 10:58 am
Does anyone know the valve diameters for the various 175 motors?
I have a 175TS and gave up on my "sports" camshaft as I think the valves are too small to get the proper benefit from it.
I have seen a head advertised as a 175 Sport head, with valves 31.5mm exhaust and 34mm inlet.
I don't seem to have a note of mine, and the various books I have don't tell me either.
