Intake gasket

Those look like 273/318 gaskets. The ports look almost square to me. The 340/360 ports are much taller with a rectangular look to them. Frankly I’ve never used a tin gasket on a 349/360 intake. Kim

Well I may have just bought some useless gaskets. Isn't the first and won't be the last. Thanks for your observation and response. Jeff
