Unstoppable Coolant Leak

Another thing- I've been torquing the intake in two steps to 23-25 ft-lbs (Found here: Dodge Magnum Torque Specs ). BUT, my intake is for the most part a chinese copy of the edelbrock air-gap with both head patterns drilled. I looked up the instructions for that to see how they recommend installing it and they only say to torque to 12 ft-lbs! https://www.jegs.com/InstallationInstructions/300/350/350-7577.pdf
Did a little more digging and saw a few other things that said that.

Thinking on this, I realized I was torquing to ~23 lbs initially- small leak. Retorqued to 25lbs (eighth to quarter turn more)- bigger leak. Overtightening may have been borderline okay before, but with the heads milled it's causing havoc not letting the gasket take up the newer difference in angle. I'm hoping I'm onto something with this. When I get home I'll loosen everything and get it to edelbrock's spec and let you guys know if it made any difference. Hopefully everything should still seal.


I have never torqued an intake manifold in my life. Not on the Hemi (gen 1 and 2) or anything else. I snug them down with a box end wrench. That's it.
