Here is a selection of some of the camshafts I have modified for use in some of the engines I have built starting from Briggs and Stratton lawnmower engines
SuperCharger, Monosoupape, UniFlow 2 Stroke, Full speed UniFlow Camshaft

Sorry, I don't know anything about the Vanguard engines.
However, generally to modify the camshaft (assuming it is made of cast iron or steel) You would first need to look at the valve geometry, to make sure the engine can tolerate more valve lift, without hitting the piston. Then note the existing camshaft duration and lift, and weld on more to achieve what you want. Getting a smooth camshaft will be the hard part, lots of filing and sanding, and trial and error! :)

Yes, I did machine it on a bench grinder! :)
You must understand though, that the engines I use these cams in don't generally run very long. so they are fine for that purpose. Other than filing and sanding the lobes, I have no other way of smoothing the surface.

can i weld some more metal on the flat tip of the lobe? (stock cam) and will it increase performance? or hit the top of the head?

You would have to check out the engine. I use modeling clay, put a small piece on top of the valve, and crank the engine over slowly, it will squeeze it to show you the existing clearance. Of course you might be in for a new head gasket, but the is the price you pay to modify things.
