How big of a cam can I use

I have a set of old MTI heads 853 castings with 2.055 intake valves. How big of a cam can I go with the big valves with out fly cutting ? Heads have no milling

Bigger valves really dont make hardly any difference in ptvc as they are at an angle. Probably less than .005" or so but i'd still check it. trex is biggest on stock setup.
