As the title states, just rebuilt and painted my motor...finally......anyways, puting tranny on and noticed 3 threaded holes on each side of the block by the knock sensors, what are they for??? I dont remember taking anything out of the old motor or seeing that these were missing? Looked on google and says something about 'girdle' bolts for the main caps???.. Pic inlcuded. Please help. Also i need a ported TB and have left messages for people to no avail. Main concern is these threaded bolt holes....looks like oil would leak.
