These Cylinder Head studs are of the type fitted to 16H and Big4 Side Valve engines from 1948 through to 1957 - an original Post War WD16H cylinder head stud being used as a pattern.
Price is per stud. Normally 9 are required for a complete SV Cylinder Head.
We have CNC machined these from stainless steel, using an original Post War 'New Old Stock 16H cylinder head stud to ensure we got the lengths of thread going into the barrel, and protruding from the cylinder head, as per the original Norton stud.
When used in conjunctions with our SV Cylinder Head Nuts (Item 1130), they transform the look of your cylinder head, and if your originals are chewed, make working on this part of the engine far easier.
This cylinder head stud differs from the Pre-War type (Item 1131) fitted up to 1947 models, as for 1948 both the OHV and SV engines received a complete make-over, which included the Side Valve models getting a re-designed alloy cylinder head, which required longer (deeper) studs. See in the accompanying pictures - line drawing fromt the 1948 Spare Parts list, showing this type of stud, and the photograph of our stud and cylinder head nut (Item 1130) alongside 'New Old Stock' originals.

If you have a Pre-1948 Side Valve model, then see Item 1131 instead, for the stud design fitted to that later engine
