Can you tell me why AFR recommends this? Surely the chamber is not over 4.0 inches. When I called AFR, they tell me it is because of the chamber size.
I have a 4.000 inch bore engine and I run a 4.010 inch gasket. The heads are Livernois, but basically 243 series heads.

AFR does have small bore heads, those need a 4.000" gasket.
Combustion chamber has most to do with it, if its CNC or hand finished best to measure.
GM 6.0 gaskets are 4.050" gasket bore, on L76 engines GM uses a 4.100" gasket with 4.000" bore (LS3 heads chamber are around 4.100")
