Default Head gasket availability

I'm looking for some head gaskets to fit a 4.030" bore but haven't had any luck finding them. Does anyone know where I could find some? Someone suggested getting 6.0 head gaskets(4.000" bore) and have a machine shop open them to a 4.030" bore, is this safe to do? Thanks for any help.

I'd check out Cometic head gaskets.

Are you NA or FI? What compression?

I believe the problem with the cometics is using them on the earlier style heads that have the notch in them...they cause coolant to leak out where the notch is.
