Height of this stock port gasket is 1.48"and its width is 1.78". Designed to improve the sealings. Superior tensile strength. Gives the gaskets the ability to conform to warped flanges. Better sealing capabilities without cracking.
Tightened them up, not sure what's going on but they were still leaking when I put them on for the first time. after a week or so they seem to settle down. I do not know what it is.
