Warped Aluminum Weiand Stealth Intake!

Took off the old 2 Barrel iron manifold on my 318 and installed a Stealth manifold.
I couldn't believe how much it rocks in place from corner to corner. Chasing from one side to another. I finally got a compromise position and torqued it down but worry about internal coolant leaks. Thanks for any advise.
