318 with 360 heads milling : small valves

I milled a set of 360 heads .060” off the deck surface and .050” off the intake surface and gained a full point of compression on my 318. 74 motor with pistons near .100” below deck. Chambers went from 68cc to 57cc with 2.02/1.60 valves. Not worth the $$$ or hassle in hindsight.
