Fel Pro 1003 Head Gasket Coolant Hole

Is your 327 engine hi-performance, have aftermarket heads? The fel-pro Q1003 head gasket is a hi performance gasket. The hole is in the gasket because of the two exhaust valves that are side by side in the center of the head. This area puts out the most heat. Line the gasket up on the head to see if it has a hole drilled. If not the two smaller holes will provide coolant for this section. The stock factory replacement gaskets do not have these holes. If you want to drill the holes, tape up the cylinder bores and put some heavy grease on the deck and drill bit while drilling holes. If you have a shop vac have someone hold the hose to catch excess shavings. Nothing to it!
