Bain, are you sure about this?? Maybe cam w/stantions oughta be pulled by cracking the chain and pulling cam stantion headbolts but leaving the rest alone. Thats the procedure for pulling em on m180's. The idea is to keep each stantion matched to its camshaft bearing. Ye never wanna mix and match cams and stantions.

Otherwise, Toms 100% correct about worn camshaft lobes and/or rocker surfaces not bein instant death to the engine. Reconnoitre tougher starts, stalling if yer wife pumps the gas from standing start, slightly weaker engine performance - thats all.
