Finishing touches: carb, push rod, rocker questions

Just purchased a build.

429 with 11:1 compression.
Isky Cam (254 duration, .590" lift, 108 lobe center)
Heads: pro comp alum...kidding. I have fully ported 69VE castings. Machined and assembled by Lesco.
Have all receipts for everything done totaling far more than I paid and needed power plant for my 72 Thunderbird (HEAVY muscle!)

Came with Holley Ultra XP 750 . (Thinking this is too much carb for street driving) obviously not taking this yacht to the strip.

Needs push rods and rockers, and carb. Thoughts/ideas.

Goal is a big nasty loud muscle car. Not grandmas t-bird.

Rough estimated 525hp.

Found a c6 with a looser converter (2500 stall) that I’ll mate to it.
Need to find driveline.

With a heavy car like that, you want to concentrate on making as much torque (low RPM) as possible.

With the iron O.E.M. heads I would use the Lunati "Voo-Doo" rocker arms. Pushrod lengths should be around stock length but, should be checked.

Thanks!
For carb options... ultra xp 750 right for this or sell it and look at...?

The XP 750 can be made to work but a 750 cfm vacuum secondary is probably more appropriate.

Which intake manifold?

For the power he is looking to get, I would use a Trick Flow "Track Heat" however, for the use it will serve, I would get a Performer RPM.

I have performer RPM.
