Head help....

Ok, Dart Sport 408, small valve jheads, air gap intake, Dougs headers, 484 lift/ 279 comp cam, 750 Edelbrock carb, Revinator box, 2500 Hughes converter, Cheetah valve body in 904, and 8.75 with 3.73 sure grip.
So I built this car to mostly run to shows and work but wanted it to be fun at the track. I finally ran it for the first time last weekend and was very happy with a 7.96 in the 1/8 with a 1.73 60 ft. This is all steel, full tank of gas, and even the spare tire. I haven't done much with fine tuning yet but that will come
My question is how much do I really stand to gain with a set of say Edelbrock heads over my small valve jheads? My over all goal at this point would be to run A little faster time and keep it consistent. I'm thinking I would like to stay with the same cam because it's very street able and really unassuming. Thanks

I'd say you stand to pick up a good .5 seconds if you make some changes. Think about it, not only are you gonna get more HP from the edelbrock heads, quite a bit over small valve heads, but you're gonna drop ~30-40 lbs with the iron vs aluminum heads, drop the fuel level down to about 1/3 of full, ditch the spare tire and even remove the rear seat, you probably knock 150 pounds out of the car. 100 pounds saved is equal to a .1 on the tree supposedly. combined with .2 to .3 seconds from a better tune with more HP. I'd say if you've got the money, may as well give it a try.
