Default Afr 205cc which headers on c5 corvette

There are a set of afr 205cc heads on a c5 zo6 I just bought. I'm eventually throwing a good size cam in it as well. My question is, which would make these heads shine more with the cam. 1 3/4" or 1 7/8" primaries? Im looking for overall power gain. Sorry if this has been covered. I'm on my phone and can't get search to work.

1 7/8 without a doubt. Get that size and don't look back.

Kinda what I thought but figured I would check. Just wasn't sure with those small bore heads which would be more efficient.

1 7/8 headers are going to make more power on a bolt on only car over the 1 3/4 headers every day of the week and twice on Sunday. Those AFR heads are badass and you'll want the larger primaries to expell all the air they will flow.
