Ken, any BBc head gasket should work, just need more the bore size? I would use Felpro 17046 gasket for that myself. On my ZL-1 I used COMETICS for my use.

Also, check out my thread about ZL-1 blocks:

FYI if yours IS a "Yenko" block, that would seem to indicate it's a 1976 or later block. Then the "053" seem to be from the mid 1980's era as per the guys on the thread.

Good luck, John
