Simple: See what's in-stock immediately available for wrenching this week

One side-note: Sometimes when manifolds get ported they slightly warp due to heat and the flange face isn't as true as it was from the factory; the white gasket allow for more squish than the OEM gasket does. Cobb had this issue with a ported IM (MAP Rev2) and the OEM gasket wouldn't seal it.

Well that was my thoughts as to why the leak is there, because I got a MAP rev3 since last time it was isntalled. So I assumed the white gasket I had was formed to the OEM manifold and after the porting, the surface changed slightly and it wouldn't seal.

If they have the white one in stock I will go for that I suppose. It's not the end of the world to do the IM twice I guess. And if it has more "squish" than OEM, that is probably a good thing.
