225 slant rebuild for more power

I’m looking for an intake right now I’m thinking Aussie speed long runner 2 barrel and Holley 350 avenger. I think this will be a good combo for the regrinded cam new lifters and 318 springs. Going to deck the block shave the heads and new rings and bearing hopefully I can use the same pistons they haven’t got back to me yet. I haven’t even thought about carbs and linkage yet but I know jack about carbs so please hit me with some knowledge thanks guys hope you all had good holidays.
Intake i would say super six or offy four barrel intak, kickdown and throttle cable will also need to be redone early veight darts barracuda valiants or slant six would have the throttle cable pedal that bolts in your wagon
