question is, they told me that they might not leak when they're cold but once they get hot they might.....Is that true ? If so do they test them under heat ?

Yes, that is true.
You might want to test them yourself... You'll need warm water, propane torch and a small water valve.
Hook up the water valve to the outlet on the header and hook up the hose to the inlet hose on the header. run the water until all the air is bled out of the header and then close the valve. Once the valve is closed, heat up the inside of the tubes around the exhaust flange, also use the torch to heat up inside the collector area... check for leaks...
You will probably also need a small flashlight and a mirror.
Check them thoroughly and check them often!

Buizilla has it right, fill with air & submerge. We have a 50 gal drum we use.

Everyone has their own method though...

Sometimes using air alone will not have a leak show up. When heat is applied the metal will expand showing the crack.

your absolutely wrong, it will absolutely bubble, but i'm not going to argue... I just went through this last week on 9 cast manifolds, and if you doubt what i'm saying come on down and i'll prove it.. the manifold material or the leak location is irrelevent, a leak is a leak...
When it's submerged in water can't see inside each individual pipes to find out where the leak is coming from, so good luck having it repaired properly..
Do whatever you want and whatever works for you....
Exactly.....
