500cc SOHC 11/32" Stem Inlet Valves (Sized - 4.590"\\4.625" Length, 1.735"\1.750\790" Head)

High quality inlet valves manufactured by G & S Valves - Following Head Sizes available (check your original) : 1.735", 1.750" or 1.790" diameter. Standard Model 30\40 stem diameter : 11/32" - Stem length: 4.590" or 4.625" available, both with collet groove already machined.

1.735" was a STD Norton valve head diameter on many SOHC 500cc models, and the 1.750" variant is only 15 thou larger and is the most common variant - as most cylinder heads will allow for this size, particularly if the valve seat has been re-cut.  

0033B_2 is one of most commonly purchased valves by SOHC customers

These valves already have the collet groove machined and are ready to fit. Note: Norton cammy valves were made in a variety of lengths over the years, however, this length - 4.590" is one of the most commonly used. If you have an original then measure that. If you are unsure please email me.  You will see we also sell Exhaust valve variants which also have a 4.590" length (as always best to buy as a matched length pair). 

Note:  We also sell Item 0033C which are a very similar valve - 11/32" inlet, 1.750" diameter head, but with a slightly longer length of 4.650" - whcih was another common length, and we also sell exhaust valves in that length as well.
