318 intake gasket

well appears i have a bad intake leak that has been causing me problems. ie..running ruff, idling ruff ect. it is an older edelbrock rpm low rise intake my question is what gasket do i need to go to the stock 318 heads? any thing special or can i use a stock style gasket. obviously i will use RTV permatex for rear and front but the intake runner gaskets need replaced asap.
