    Are the s/c cylinder heads and N/A heads the same and/or interchangeable?

    I have the 00' Buick GS and 01' LS, i wanna know if the cylinder heads are interchangeable

    Correct me if im wrong, but i think the bottom end of both motors are the same
    Not your average grocery getter, but theres always at least two things on the list.... 10w-30 Castrol Titanium and Shell 91 premium mixed with a lil 100 octane racing gas......

    No, they're not the same. L36 heads dont have injector holes in them, L67 heads have holes for the injectors in them.
