Fig. 629 shows the new design one piece intake and exhaust manifold gasket A-9448.
The new gasket obsoletes the old style manifold gaskets and glands as no glands are used with the new design, the gasket being held in place when assembling manifold by means of the studs on the side of the block.
This change will eliminate the counterbore for the glands in both the manifolds and cylinder block. The new gasket can be used on both old and new jobs.
