Need advice on 429

Hello all, I am brand new to forums so please forgive me if I am posting wrong. I have read through many threads on this subject but am still somewhat confused.
I want to put a 429 and C6 in my 71 Mustang and need some engine advice.
I have a 72 429 out of a Thunderbird with the junk D2VE AA heads.
I have a bare set of DOVE-C heads I could use. I know they will physically swap, but the rebuild book I have says the resulting compression ratio would be 9.7, this seems a little high for pump gas.
What I would lik to know is:
1. Is this a good swap to make ?
2. Can I use the valves, springs, etc. from the 72 heads in the DOVE heads ?
3. What should I use for rockers, push rods ?
4. Camshaft recommendations ? (would like around 400-425 HP)
5. Intake/Carb recommendations ?
6. Should I use a stall converter in the C6 and how much ?
Thank you, any advice will be greatly appreciated!
