Budget 318 build

The purpose of my car is just a fun cruiser I'm not gonna be racing it I just want a street car that will have enough power to get me around and be fun to drive lay a black mark or two and not get out ran by a 91 Buick as someone here put it lol! Thanks for the input I'm just trying to get the best bang for my buck make it run better than stock without spending a fortune. Oh btw by cut do you mean mill? Or port? I wish I could find a new factory gasket lol
cutting the heads means milling. My opinion, I would hate 3.73's if it spends some time on the highway unless you have Overdrive. Go out and put your car in 2nd gear and go 60 mph, because that is approx. what it will sound like going from 2.76 to 3.73's.
