What are some ways to add horsepower to my setup? 1972 Luxury Lemans, 455 bored 0.030 over, #96 heads 3 angle valves, flat TRW pistons, 9.3:1 compression estimate, Melling 26308 cam was set at zero, iron intake, quadrajet by Cliff, curved ac delco hei(sun machine reading attached, not sure what it means), ram air manifolds, 2.5" dual exhaust, 3.73 gears with Eaton posi, 200r4 transmission, 10" billet 2800 stall. Downside, I am not sure if my rods are forged. The paperwork says 496453 crankshaft, polished standard sized rods and mains, rods resized with ARP Bolts.

Not looking to rebuild my motor as it has about 3k miles, but it's not as fast as I was hoping when I put it together. What would be the best way to get rid of the laziness on the line?

My ideas and questions.

1. Advance cam to 109, 4 degrees or
2. Boost compression by adding kre heads if it really would make a noticeable difference over the 96 heads. I was thinking the 74cc heads maybe at 290 or 310cfm ported.
3. Have my 96 heads reworked.
