well if you bored it .060 that means the new bore is 4.060 and there are lots of standard gaskets out there that fit that bore size.

Folks ... when you see a head gasket speced for 4" ... that simply means it's speced for those in the family of 4" bores. AFAIK ... there are NO off-the-shelf gaskets for a 302/327/350 that have an ID of 4.000". You'll find, most have ID between 4.100" & 4.200" ... often Not round but irregular"... typically about 4.166".

A good gasket choice for either IRON L48 / L81 / L82 HEADS is Felpro p/n 1094 ... bore=4.100", thickness=0.015", volume=3.2cc, rubber-coated steel shim. there is only one gasket per pkg ... order two for a rebuild/overhaul ... you can get them thru most local parts stores.
