accord83 372 Report post Posted Monday at 17:24 I'm just changing the cylinder head on my flow and I noticed that the exhaust side of the block/head has 3 coolant holes that the old head gasket covered over, so I checked 2 new ones on my shelf. Just the same. So I looked at the pictures of a Felpro gasket on Burtons site, the same. What's that all about? Why have water galleries which match, and the block them off with the gasket? Is this correct or is it time for the hole punch to be introduced to Mr Headgasket? Share this post Link to post Share on other sites

katana 368 Report post Posted Monday at 18:00 Varying the hole size is a way of restricting or varying the flow around each cylinder. You often see smaller holes near the pump and larger further away. Share this post Link to post Share on other sites

One of my spare gaskets has pressings around the 2 outer holes as if they were optional to cut out, bit weird. Share this post Link to post Share on other sites
