13.3's to 11.8's to Forget it...

Heads : With the low compression pistons in your engine i think you are going to need a very well ported / good flowing set of 360 cast heads or the promaxx alloys (also well ported) so you dont need to big a cam which wont like the low comp and then have to run a very low set of gears.
My suggestion would be as small a chamber head as you can achieve without milling them too much. Edelbrock rpm or the stealth inlet should get you there.

Camshaft: around 240 at 50 solid flat tappet camshaft.

Gears: 3.91 gears,run your 26" street et at the drags and something a bit taller for cruising.eg 255 60 15. 3000rpm at 60mph with the 26" tyre. Alternatively you could run a 3.73 or 3.55 gear with a very small diameter tyre at the drags to lower the effective gearing.

Converter: reputable brand with 3500 to 4000rpm stall.
