Project 65 chevy k-20

Whats going on everybody? just thought id drop by and see if i can get a little bit of insight . My current project is a 65 chevy k-20 with a 283 sbc thats original to the truck. Went thru some updates with the brakes and suspension but now im focused on the motor. I dont mind having the small block but i was hoping to pry a little more power out of it without loosing the cl***ic look to it. Im thinking of going with the 3795896 power pack heads and a triple 2 barrel intake. Just looking for any fresh ideas. Thanks
