Guest Posted June 5, 2001 Share Posted June 5, 2001 I own a 1969 skylark with a stock 350 with a holley 2bbl carb. Im installing all new gaskets from the heads up and i ran into a tiny problem. I noticed that a part of the head gasket covers a water port thats below the the #1 cylinder on the block. I looked in the TA performence catalog and their copper head gaskets were exactly the same as the Felpro gasket for the exception that there is a small hole in the flange that covers the water port. I was wondering if i could drill a small hole in my gasket and would it make a difference or would i hurt anything.I talked to a guy at Vic Hubbards auto parts and he said that flange might be there to redirect the water else where in the engine.Although i noticed theres a port in the head also where the port onthe block will match up . Please help me Link to comment Share on other sites More sharing options...

Guest Posted June 8, 2001 Share Posted June 8, 2001 If you have the correct gasket for the appropiate application, then install them as is. It is not a good idea to modify or alter a head gasket.<BR> Doing so can compromise the intergity of the gasket's sealing efficiency and lead to further problems.<BR>There probably is a good reason for this gaskets specific design.<P>Ron Joseph<P><BR>Ron's Custom Auto<BR>Merkel performance Engines<P>1-800-718-7667 Link to comment Share on other sites More sharing options...
brad54 Posted June 8, 2001 Share Posted June 8, 2001 Trust nothing! There are many, many instances when a major manufacturer of parts makes a blunder.<BR>What'd your old head gasket have? If that's the original gasket, I'd go with that as the template.<BR>Call the guys at TA performance and see what they have to say.<BR>I can't see Buick putting a water passage in a block and head, and not really needing it.<BR>-Brad Link to comment Share on other sites More sharing options...
palbuick Posted June 8, 2001 Share Posted June 8, 2001 Why not go directly to the source. Call Felpro, they are located in Illinois and should have a 800 technical line.<P>Jim Schilf / palbuick@aol.com Link to comment Share on other sites More sharing options...
