simple question - are they the same?

Not so simple, what brand of head gasket are you using? Is it a proper F54/P90 turbo motor?

From what I've read the F54 block/head has extra water ports, some gaskets block these off, some don't. The ACL gaskets look like they have the extra water ports but the Permaseal one doesn't, there will be two different factory Nissan gaskets.

it's the turbo motor in my Rat Z - Has an N42 head but i have to check what block. The gasket is one online - not sure of brand. They current one hasn't blown as such but is leaking in one spot around the edge. Going to investigate a bit more soon. Cheers for the info
