Head gasket bore size?

[sc440]

.030 over 440 so 4.350 bore, tf 240 heads. What bore size head gasket should I order 4.410?

For 440s I go for a larger bore, like 4.500". The compression difference is too small to worry about between the two sizes, and many of these old blocks have some pretty big cylinder chamfers. Just my personal preference.
