360 build up advice

I've been reading the threads and I must say theres an unbelievable wealth of knowledge on this site.

I have a lil red express that Ive owned for years which currently has 3:55 gears, 727 and a 360 with cast flat-tops (about 9-1 comp.), LD340 intake, factory TQ, Mopar 450/455 lift camshaft, a set of worn out 2.02 J heads and headers.

I want to upgrade to a 60403 lunati camshaft and add a set of RHS LA-x heads instead of rebuilding my J heads (it's probably the same coin and I figure I get a better performing head).

One of my questions is that it's going to be a street motor with the factory valvetrain so would the 1.92 valves be a better choice than the 2.02's - I was told that I probably wouldn't get the flow advantage of larger valves without a high rpm smallblock - I would like to keep low end torque for the truck.

The other thing is I am thinking about a swap to a 750 eddy carb

Any info or advice would be greatly appreciated - Thanks
