I Have a 99 Trans Am w a Ls7 Top End 427ci, I also have a set of Kooks 1 3/4 Stepped to 1 7/8 x 3in Collectors on it....The Ls1 exhaust gaskets wont do the job, Question is will the Ls7 Exhaust Gasket work for this?

Im sure somone on here has ran into this before..

Only other alternative is to Sell the Headers and have Kooks make a custom set which is pretty pricey
