I'm looking to improve the performance of the motor a bit, and have considered the following options within my current budget. The motor is currently an standard bottom end 454, oval port heads, edelbrock dual plane intake, unknown cam type, tri-y extractors, high torque starter, weiand team-g water pump, alloy radiator, B & M gear drive, Romac hi-perf balancer. I don't have exhaust system run yet. I'm considering twin 3" if i go the procharger route, or twin 2 1/2 if i go N/A.
1) Purchase alloy head / intake manifold package - I'm not sure what size and brand to go with for a mild street combo. What size chamber / runners should i go for with my type of use? Edelbrock seem quite cheap in comparison to everything else. I want to retain stock exhaust port height so that i dont have problems with my extractors not fitting up etc.
2) Purchase pro-charger F1-SC series package direct from ATI - This looks really attractive to me, but how well will this perform with a set of oval port heads?
Will I have nightmares with the carby trying to get it running well with the pro-charger setup?
I would be getting a lot of weight off the front end by replacing the iron heads with alloys.
Thanks guys, I've had a fair bit of experience with small block ford stuff, but am pretty new to Big block chev stuff. I just want to make sure I spend my money wisely, as i dont have a massive budget.

Check out the GMPP "Roval" ports. 290cc intake runners good low and midlift numbers. Well designed head with stock exhaust port location.
Combine with a big lift (.600s) hydro roller and beehive springs for a snappy street 454 that will rev if you want.
You might have to clearance the flanges on your headers to clear the outermost row of head bolts, but any alloy head with standard ports will have this problem.
