Problems after Cylinder head Port & Polish

[juiceman]

its good to hear you got it going good again. as for running hot, it may be a little lean but you dont want to change the idle mixture maybe jets on primary side. but as with anything more power means more heat as heat is a byproduct of power. also with the advanced timing it will add heat. mustangs are known for running hot so dont worry. if it really bothers you get a better cooling system.
