Boost on lq9!! What heads?

Hey there guys almost done with a project but do have a couple pair of heads laying around. Got some 823 rec port untouched and some 862s cath port. So I?m gonna be shooting for 750ish for now will start off around 10psi. Do plan to go up on boost later. Do have a boost controller but haven?t used it yet, so that?s part of the plan.
Question is what heads do you guys think be best??

It honestly doesn't matter than much, both heads will make 700+ horsepower with ease on enough boost.

Likely the 823's flow more air but then you'd need the matching intake for it.

Thank you for the reply, yes got matching intakes for both heads. Stock for 823s and a Holley high ram for the 862s. Im thinking of just flipping a coin on it lol.
