72 Duster Street / Strip Build

Picked up a set of bare 4027596 360 heads, plan on cleaning them up and doing some minor porting work. These won't see the current 318, but will see use with the 360 build along with the airgap intake. I figured picking up a set for $25 with a pitman arm trade wasn't a bad deal. Will need to find valves / retainers / springs to match the cam / seals... Should I cut them for larger valves since I am buying new or keep the 1.88's? Thinking cutting them for 2.02 intake would help with a 360+ cube build in the works, but it will never be a real high rpm screamer 6000 rpm .5xx" hydraulic cam setup.
