ALERT!! SOUND THE ALARM!!..

Ok, I was either going to kick myself If I missed the deal, or my wife is going to kick me if I did, Either way I was going to get kicked, so ordered a set of bare heads, studs and 1.5 stainless roller rockers. Now we need to get recommendations on good valves to use! Springs will depend on cam choice. I have a 30 over 318, Performer intake, 650 Edelbrock carb, but no clue on cam, compression ratio etc. was in the car when I got it. I added a set of Dougs Headers and 2.5" Pypes Exhaust. Heads on it currently are 360 cop heads according to the number. So probably do some clean up and gasket match on the SM heads, slap either ld340 or ld4b ( I have both) on it and call it good. Car still has 7 1/4 rear end. It's convertible that I'm converting to 4 speed, but will be just a cruiser/street car.
Those small chamber aluminums should perk up your teen a bit I would think. I don't know how your iron heads flow but these are as good or better by far and a increase in compression will help your bottom end.
