Ya I had a old 2f out of an fj60, that had and exhaust manifold that I rebuilt and put a 77 fj40 intake and all new hardware. That's probably what I'll do tbhIf it’s of interest, I just run the stock spacer under the sniper with no heat shield and I don’t see any issues with it. I also have hard lines all the way to the sniper. But mine is also an F engine/intake with no bolt provisions for the heat shield.
