Anyways:rolleyes:... I should have both the gaskets in post #869 the cometic and the Edelbrock / fel pro by Tuesday and Wednesday... So hopefully Wednesday night I'll be able to lay one over top of the other and see the difference...
Okay so I got my Edelbrock gaskets the 7326 which is a which I believe is the 180 / bore with the 50 thickness...
Also I got the cometic c5633-075 which is a true 50 over bore and a 75 thickness.. I laid the two over top of each other and seen near 0 difference then any of the oiling or cooling holes...
Now I'm waiting for my cometic c-5622-070... Which is a true 90 over bore at a 70 thickness and that is the one that I want to use. If that one lines up with the Edelbrock gaskets I'll send all those back and keep the 70 thickness...
