B16a header blocked by b18C1 bottom end

So I put my B16a stone racing headers on my engine and they do mount no issue however the bottom of the pipes by the o2 sensor hit the bottom of the oil pan when trying to seat the headers properly to the head. No matter how hard I try I always get a manifold leak really bad. The problem is they don’t go down enough but it’s off by less than an inch. Is there any trick to maybe bending the pipes down a little?

This. The B16A has a shorter deck height than a B18.

Yeah I know I need b18 headers I was hoping maybe there was some way to bend the down pipe a little or something. I don’t wanna break them though And I have b18 headers coming tomorrow
