only 500?
I'd use AFR 205s as well.
Intake, I'd use a

I like quality, it's my thing, so here goes the quality adders:
Billet crank and rods and a billet steel crank girdle
Custom forged pistons for tighter top ring fit, so that the vertical gas ports do their job better, and you can run lower tension rings.
Also on these pistons: Jet-Hot low-friction coating on skirts, thermal barrier coating on crowns.
Personally I would rip the heads apart (I thought they came without valvetrain components) and get Ti retainers, roller-rockers and a nice billet aluminium girdle for each side.
Valves: coated with low-friction coating on stems, thermal barrier on heads.
Camshaft, no real idea on specs, but it would have lobes and bearings coated in some low-friction stuff as well.
I would add an oil accumulator, like the Canton one, with an electric switch, so it turns on and off with ignition, inline with an oil cooler.
For an ignition system I'd chuck in an MSD CPC (coil per cylinder) DIS.
Injection computer: Accel DFI 7
BTW, I want to build a 302 - 331 stroker with the above stuff to put in a 69 fastback with the same gearbox and diff ratio you have mentioned... nice choice
There is a lot more detail I can give you, just tell me you want it, and I'll email or pm or something.
