Ford 351C Head Gasket Orientation Diagram - 1/2" & 5/16" Coolant Hole Locations

This document is a scanned illustration showing two engine cylinder head gasket outlines, each depicting four cylinder bore openings and various smaller bolt and coolant passage holes. The purpose of the diagram is to identify the size and location of specific coolant passage holes so the gaskets can be oriented correctly during installation. On the upper gasket, whose "FRONT" is marked at the right side, two marked holes are labeled as ½-inch holes and one is labeled as a 5⁄16-inch hole. On the lower gasket, whose "FRONT" is marked at the left side with an arrow, one marked hole is labeled as a 5⁄16-inch hole and two marked holes are labeled as ½-inch holes. A reader can learn how to distinguish gasket orientation (and left versus right bank placement) by comparing the positions of the ½-inch and 5⁄16-inch holes relative to the front of the engine. The diagram contains no text identifying a specific year, make, model, or engine, though the uploader filed it with other Ford 351 Cleveland reference material for a 1972 Ford Ranchero. No part numbers, torque values, or additional specifications appear in the scan.
