Over size bore head gasket

Friend has bored '72 Chevy 250 CI from 3 7/8" to 4". Now, where can he find a suitable head gasket.

ummm, i am an engin guy, and i have no clue what you are talkin about, how much overbore did he have machined

Cylinders were bored .125" over the standard 3.875" bore.

Sorry then, i can't help you

Actually, call fel-pro, or cometic and ask if they make over bored gaskets for your motor.
