Copper headgaskets - width at skinny part between cyls ?

[Special Coupe Frank]

I just received from Snyders my new head gasket, moly-studs & nuts, and tapped water outlet for my '28.

I've read commentary about Fel-Pro and their "R-3" copper gasket which was designed to work on engines with large re-bores (0.100"), which leaves less gasket between the cylinder bores between 1 & 2 and 3 & 4.

Does anyone have a width on the stock gasket at this spot ?

( I have a blown R-3 I can measure...)


Thanks !
