Wastegate advice for LS5.3L

What is your advice for a wastegate on a single turbo setup on a LS5.3l?

I'm using a Holset H2 for my turbo and looking to make about 800hp.
Would it be best to use a small 38mm waste on each of the truck manifolds or a larger 50 or 60mm wastegate right where the crossover pipe merges at the turbo flange?

Here is where I am right now in my '57 Chevy Truck.
Thanks for you suggestions.

A holset H2C is a 62mm turbo. Good luck making 800 HP with that.

Maybe split the difference with the standard 44mm gate we all seem to use
