Where to find thin .030 or less head gaskets for 4.070 bore

My decks have been freshly machined. The heads are new Edelbrocks.

Fishy68, do you remember the bore size of the P4120094 gaskets you used? Where they orange or white?

You should be fine then. I didn't have my block decked cause it appeared ok. That was probably my mistake now that I look back on it.

Mine were orange and since it's been about 3-4 yrs. I don't remember exactly how big the bore was but 4.18 comes to mind. I think I have another one of those gaskets around the shop somewhere. I'll look tomorrow and see if I can find it and let you know the exact specs.
