Head Gasket Bore Size Question

Italian LX · 09-27-2006, 09:35 AM

I'm going order me some Cometic gaskets soon for my 418 project motor. Previously, I have only used Fel-Pro 1011-1 and 1011-2 gaskets so I never had a choice of gasket bore size.

My question is whether I just order the size to match my machined bore or do I go larger for any particular reason. It seems like I would obviously order a 4.030 head gasket to go with my 4.030 bore, but I just want to make sure that there would be no reason to buy bigger.

Here is the gasket I'm looking to order:
