327 build help

Hi,
I'm looking at rebuilding a 327 and could use some help on part selection, the car is as following:

CAR:
1965 Corvette (to far gone from original to go that restoration route)
M21 4 speed
4:11 12 bolt posi rear end
Weight 3200#

Engine:
327 l79
original block .030 over
heads double hump with 1.94 valves (not original or correct)
2.5 in ram horn exhaust manifolds
zz4 intake
eldebrock 600 cfm carb

Goals:
weekend driver, no racing intentions, I'm more interested in driving winding roads but would like some off the line performance.
325-350 hp
350 minimum torque (I do understand that this is a 327 and not a 383)
$ 2500 to $ 3000 budget (hopefully including machine work)

Intend to keep:
Block
crank
Rods (if feasible)
carb
intake
2.5 in ram horn manifolds

Intend to replace:
Cam
heads
pistons
and other required items for a rebuild

I am pretty set on keeping this block as long as it checks outs and would like recommendations for heads and cam replacement. I am willing to consider aluminum or cast iron heads, weight is not a real concern to me, also what kind of intake flow values should i be looking at for the heads? (I have looked though previous posts and have a basic understanding of high vs low flowing heads, so thinking on the lower end, just not quite sure what target should be.)
I plan on lowering the compression of the engine to be pump gas friendly (91 max octane in California). I'm assuming that this would be accomplished through different pistons. (present pistons are the 11:1 comp. l79 327 sbc). If my goals are unrealistic please let me know and your help is appreciated.
