I'm gonna be putting my 383 together soon and was wondering......will the stock Fel Pro gasket work. I ordered mine and it came with the 9966#. The block is being punched out to 30 over and I was also wondering .... will the gasket fit or will I have to make some mods?

Thanks.....I know its probably a dumb question but I just wanna cover my bases before I start putting her back together.
