1967 Barracuda 383 tuning tips

Hello. I have a 1967 Baarracuda with a swapped in 383 from a 1964 Chrysler. Its now stock apart from a holley 700 carb and headers.
Im looking to get a set of good aluminium heads, another camshaft (roller?) and maybe a slightly bigger carb, like a quickfuel 850 wich i have had good experience with in the past.
And also roller rockers, ignition etc.

I have never worked on Mopars before at all, maybe someone could point me in the direction of some good street/strip performance parts?

Ive looked a bit at the Edelbrock Performance Package, just becausr you get a lot in one kit and its pretty cheap, but i heard people before saying that its not worth it?

Anyway, i would really appreciate the help.
