Gearing ?

You "can" fit a 2.02 valve into a 302???? I think i would port the 302 and not......put a bigger valve in it.
You are wanting a eng that pulls from idle to 6000 rpm. rhoads lifters will help to stretch the power band but IN GENERAL, A pushrod motor will have a 2500 rpm power band so IF, you want a stock converter they usually stall round 1800 right? so 1800+ 2500........You are looking at a 1800 to 4300 rpm. rhoads lifter stretch it to Maybe 5400.
2.76 gears will feel right at home. But It's NOT going to pull to 6000 rpm.
You want to pull to 6000 rpm......6000- 2500.......I don't think a rhoads hyd lifter will give you another extra 1000 rpm but for theory we will consider this. Soo 6000-3500=2500 rpm range aka you need a 2500 stall converter and it will pull to 6000.
just some more thought to dance around into you head.:)

Your can put 2.02 in the head.

Engines have more than a 2500 rpm powerband more like a 4000 rpm.

If my engine peaks at 5600 rpm it still would be making decent power by 6000 rpm since small displacement with good flowing heads don't fall off after peak.

Peak torque usually is around 1500 rpm less so 4100 and if done right can be relatively flat for 1500 to 2000 under that so low end power starts to come in around 2000-2500.

I want to use hydraulic roller with Rhoads lifters and hopefully bring the low end in by 1500 rpm.

Thinking of using something like this Voodoo cam.
