welding extracts carbon and chrome out of material so the surface is much weaker when it is welded, so yes thnx for the info for a regrind level 1/2 i will concider that option.
if i wanted a level 3 or 4 cam i definitely would have bought a brand new cam core because when u need a cam like that you probably have spend enough money on your engine so the costs of a new cam core is the option to go for.
my cam needs a bit more overlap but i'm not sure. within a week i will have the exact info for a cam profile for my engine.. i wil tell my info here and we will discuss the options.
