[Spridgets] Manifold flange thickness

Listerati,
Trying to get off my rear end and make some progress in my long term
overhaul of FROG AYE, my 1960 Frogeye. The engine is now a 20 over 1275
with some porting, oversize valves and VP-SP3 cam. I have replaced the old
3 to one exhaust manifold with a Maniflow LCB, the intake manifold is also
by Maniflow, for the HS-2 carbs that came with the car.  The concern I have
is that the flange is thicker on the exhaust than on the intake.  Torquing
the manifolds until the exhaust just touches the block (no gasket for this
measurement) leaves the intake manifold with about 35 thousands play.  Of
course, this can be taken up in the gasket, but that leaves the washer on
the intake side (of the common studs) sitting at a noticeable angle, which
,if nothing else, doesn't look very cool.  The attached photo shows about
.035" of feeler between the washero and the intake manifold flange.  The
exhaust manifold is snug.

What would you do?
