You will have to take the valve cover off and inspect the camshaft lobes and measure shim clearence.
But (as Raz said) the lobes are probably worn to the point that both camshafts will have to be replaced (if you are lucky).
If the camshaft bearing caps on the head are scored, you will at least need a new head, which you could get at a junk yard, but I would also be concerned about the crankshaft main bearings.
