Hydro head on mech block water leaking

[Kazuki]

Hi. I just installed a hydro head on my 1.6  mechanical block but it's leaking water out of the second oil port I plugged I'm using a 1 notch  mech HG  any ideas on how to plug the water jacket ? She's runs great other than this leak I have.

Where the oil passage in the front of the head is needs to be sealed to the outside of the block. I used Teflon joint sealant tape, but you could use a cut out piece from a gasket like the oil fill gasket.
