Check if there are .010 horse shoe shaped shims installed in the ears between the engine block and the flywheel housing. These shims are commonly left out. Their purpose is to align the flywheel housing with the bell housing and transmission. The shims are to compensate for the gasket thickness on the lower part of the clutch housing. The shims can be added if they are missing by removing the accelerator assembly bolts and prying the ears back to slip the shims in. Most suppliers carry the shims.
