These are a set of E4456 Stainless Steel Cylinder Head  Bolts for the 350/500cc Triumph Unit Construction cylinder head. They are the 4 shorter bolts that hold the head down, they have deep slightly dome heads the same as the originals.  We are also including the 4 rectangular sectioned stainless lock washers with these bolts. As far as we know these will fit any Unit Construction 350/500cc motor.  We are also listing the rocker boxes bolts elsewhere on ebay.

Please note all stainless parts should be assembled with copa slip (copper slip).

These items are Made in England.
