*Thicker gaskets raise the intake MFLD creating end seal issues and INT MFLD misalignment.

*On a motor rebuild the manifold is machined to compensate for head and/or block decking using a thicker gasket.

*Block decking use of a thicker gasket requires excessive machining – often reducing the flange contact area required for sealing.
