[Spridgets] Manifold flange thickness

[Ron Soave]

Elegantly, get someone to make you stepped washers. Hillbilly, I’ve taken thick washers and ground down half to get a step. .032 washers (or thinner skim stock) folded over in a vise and jammed in there work as well.

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.
