Our catalog record for 06-5115 is a single line from a 1975 listing, so there isn't much more detail to pass along beyond what the part is and that it's a Norton Commando component, not a Triumph part. Valve gear work is not the place to guess on specs, so if you're rebuilding a head, call the shop and we'll confirm what you've got before you order.
