Default Ls9 Head Gasket on 4.8L
Looking to do ARP's and head gaskets on my turbo 4.8L. Any engine builders/ LS brains know if I will have problem installing these gaskets made for a 4.065 bore on a 3.780 bore engine? Looking at a .285 gap.

-Thanks guys

Gonna run these with 853 ls1 heads and 3.78 bore 5.3 engine. Was originally gonna use l33 gaskets but might as well get ls9.
