    Default LS6 intake

    local junkyard has a 70 chevelle LS6 intake. i am seriously thinking about putting it on my 454 since it is a dual plane to replace the single plane edlebrock. I know the LS5 454 has oval port heads however i have read many many times that as long as you use the correct rectangular port gaskets that it is a good intake for the LS5 engine. does anyone know the correct felpro gaskets for the LS6. autozone had like 3 different gaskets for the 70 chevelle 454 and they were all different.

    Just tell them you want Fel-Pro rectangle port gaskets for a 68/69 BB. Find the ones with the heat riser crossover blocked (your choice there). Get the gaskets that match the intake the closest.
