AJP camshaft wear

[MiniV8]

I checked valve clearances and noticed the intake lobes have started to wear out.
-Does anyone have experience, how much mileage is left with wear like in attached picture?
-I would also need advice, what is the best place to source new cams and lifters?

What were the valve clearances?

The tappets are softer that the cam shafts, so if the tappets are not dished it's likely that the cam shafts have been like that for some time and the tappets have been replaced

What oil have you been using?

High ZDDP is critical in flat tappet engines, especially ones with aggressive cam profiles like the AJP8

All intake clearances were .008 - .009
I have owned the car for twelve years and checked clearances three times, this is the first time I noticed any wear on camshaft.
All that time I have used Castrol Edge 5w-40 oil. When I noticed the wear I also thought that maybe I should have been using something else..
