Norton NOS CYL HEAD 73 750 850GD
NOS cylinder head for the 750/850 GD engine, catalog-dated 1973.
This is a cylinder head listed as NOS (new old stock) for the 750/850 GD engine family, catalog-dated to 1973. We don't have much more detail on this one beyond that description, and it doesn't show up elsewhere in our records to cross-check against. The Lucas tag on this part number in our system is almost certainly a mis-tag - Lucas made electrics, not cylinder heads, so don't read anything into that.

Given how sparse the paperwork is on this part, we'd want to look it over and confirm exactly what it fits before it goes out the door. If you've got a matching part number or casting mark on your own engine, give us a call and we can talk through whether this is the right head for your build.
As with any NOS cylinder head, condition and casting details matter a lot for actual fitment - call the shop and we'll confirm before you order.
