Do u know the reason Toyota Stopped using the Brass Manifold's mounting hardware Nuts & switched to Super grade 8+ steel ?

repeated heating and cooling of brass should cause cracks and wear of brass hard wear leading to a failed nut bolt etc.

What does an ABV do? Mark, can we make a deal on those manifolds...asssuming the exaust manifold ended up being good?
