Help with decking or not?

So i was able to get my hands on af ome eddy 60779 heads so i was thinking of going eith those on my build. After doing all the math my piston would be .012 in the hole. With a felpro .039 gasket added to that would a .051 quench be bad? Still trying to grasp concept of quench. Should i possible go with thinner gasket?
