Anyone ever have their truck manifolds warp on them? went to put my turbo kit back on today and noticed that the forward facing drivers side, the manifold that comes with the center section "pre-split" has the forwardmost twocylinders now at a slightly lower angle. Where it splits in the center is off approx 1/8" at the center forward hole, then slightly less inbetween the front 2 cyls.

Ive never heard of this happening. Only thing different is that I had them ceramic coated, but that couldnt have gotten them any hotter than they get on their own

More likely is the rest of your hotside warped and you never noticed it

That is a common thing on the old SBC for the manifolds to warp. I haven't noticed it on the ls motors though.

I know my Stainless steel headers warped on me and would have to be tweaked to get then back. My iron ones have never been removed but I think I'll have to check them closely and see. I've run the motor pretty lean at times and things heated up pretty quickly. This was due to sticking wastegates.

I ended up just porting the inlets to match the head
