I want to use it for a NA-Solution with a different intake manifold as described. But if you try the normal partshops you won´t get any result with the number above. The LSJ-Gasket was substituted in 2006 with another gasket which has the number 12597855. Another gasket which could be found is 12584359 for the lsj. So what is 12593902 for?
I want to seal the intake from the head. The pattern of the 12597855 should be good, but the holes for the bolts are to big. I dont want to drill the holes in the head bigger, when I perhaps want to change back.
So best thing would be a mix of it: seal of lsj and holes for the l61.
