Welcome! Nice Barracuda! Have your heads done right and bolt them on. Best thing you can do is pick a good mechanical cam and a double roller timing chain. Those pistons are good, they should be close to .020 below deck. Any 318 intake will work since they have the same size ports, make sure your heads have 3/8 intake bolts (9/16 wrench). It should be easily get 1 hp per cu in with a .425-.450 lift cam with good machine work. Also looks to have a forged crankshaft. It should be red, not blue. LOL
