Which head gasket should i use?

I have a 95 z28 with an lt1 bored .030 over and i have aluminium stock heads that have bigger valves (2. and 1.6 stainless steel) so i was wondering if anyone would like to reccomend a head gasket to me? thanks

If it was zero decked then the Felpro might be a good choice, otherwise though probably not. It just gets blindly recommended because it is Felpro rather than because it is right.

To make a good recommendation we need to know the deck height and target compression.

Mr. Gasket/Victor Reinz have a .026 gasket which is good for helping raise compression, would be too thin for a zero deck block.
The stock b-body gaskets are .029.
The Felpro is .039
the stock f-body gasket is .049
Cometic has a .027 with a small bore
SCE has been pretending to soon release a .021(same story as MSD opti and Edelbrock intake, Summit ship date gets pushed back every couple weeks)

Great info. I was wondering what the actual dimensions were earlier today
and here it is. I'm going with the B-body gaskets on my head install as
recommended by Ai.

Sent Summit an email on the SCE gasket and they are pretending it is available but special order.

They are a 4.060 bore copper reusable gasket.

I am using the Mr. Gasket but hate the packaging issues, the Victor Rienz seem to be the same exact gasket but individually packaged, cost just a little more but worth it to avoid the packaging problems of the Mr. Gasket.
