stock to aluminum heads

I now have 596heads 1.88-1.60 with light port work by me. They were put together at the machine shop - under cut for Crower double Springs ttitanium retainers an made to support my solid lifter 550 lift cam using 273 rockers.
Soooo, I'd like to buy Edelbrock 601719's (I'm .010 above deck) and some crane or some quality rockers.
I would have to use this stuff out of the box, as the winter budget is tight.
Would I really see a major bang for my buck over just putting 2.02 intake valves instead in the heads that I have ?
11.7 et now
justs 2.02 in heads that i have?
Aluminum heads and roller rockers ?
Thank you

i should ad it's a 410 stroker scat crank and scat I-beams icon flat tops
