Default Afr 245cc LS1 mongoose heads

Ordered these for my c5. Bottom End is a 6.2L Forged setup with Mahle Powerpak forged pistons. I notice on AFRs site is says it needs a 4.200 bore head gasket? That seems super odd and I was planning on running FaCtory LS9 head gaskets but they are a 4.100 bore. It's a centrifugal boosted C5. Will the LS9 gaskets work fine? If not, what can I get that will work? Looking for .055 compressed thickness but that 4.200 bore is trippy to me especially since my block is 4.065

That shouldn’t be a problem. Folks have ran a 4.130” gasket on a 4” bore.
