Am I right to assume that the main difference between a cga3de and cg10de cylinder heads is the cams. I am looking to fix a spare cga head with bent valves I have a spare cg10de head for donor valves. Looking at a supply catalogue it gives the same part number for the cg10de cg13de cga3de inlet and exhaust valves respectively. Can anyone confirm the valves are indeed the same before I start dismantling a good cg10de head?
