It could be a defect in the mating surfaces. It could be the installation.
Isolate the exact spot it's leaking.
I would dry the area completely (perhaps rinsing with water and then using compressed air or air dryer).
Then pressurize the coolant system system to around 16psi (while engine is cold).
Watch for the leak. Mark the spot(s).
Disassemble.
Inspect the mating surfaces. Clean up any defects.
Consider using a "smear" of RTV along with the new gasket. (Be sure there's no "squeeze" excess that can break off and circulate in the coolant system.)
Respect any specified bolt tightening sequence. Respect the specified torque.
Respect the cure time before applying pressure (whether from being pumped-up or from the engine being started and warming up).

Exactly this. When I installed a new plate there, I smeared some gasket sealer on the gasket - it's just a smear, so a very thin coating along both sides. I do the same when installing water pump gaskets. You can see it in this photo - it's the plate behind one of the supercharger brackets. You can also see there's a hose clamp connection on the right side. Make sure the clamp is tight and that it's not just leaking from that connection.

I redid the gasket with RTV and it started leaking worse. I was like WTF? Noticed that it was dripping from the top right bolt. So the next thing up from that was the small rubber hose. So I decided to take that off and replace it with a new piece. When I looked at the hose I could see signs of pink dried antifreeze about half way up on the backside.. It must have had a small pin hole leak. After swapping it out with a new hose, I have now driven a few good healthy stomps and have not seen any more leakage. ;-).
Cracking a beer to celebrate.

Still leaking coolant from right below alternator
