Looks like you did it correct. If the head checks out ok, inspect the block. Otherwise I would order new set of gaskets or try and clean/reuse your current cometics and prep them a tad different next time. Was the gasket bore larger then the chamber of the cylinder head?

What kind of boost psi are your running again? 
The cylinder wall could have a slight crack in it. A crack in a cylinder wall would not show water in the oil but it will pressurize a cooling system.
i did but did not see anything well i got a coolant pressure tester i got 26 pis on it to see if i can find any cracks or get some cule of whats going on but ya i kinda thinking somthing wrong with block but i have never seen a lq9 or 4 block craked but its my kinda of luck i will have one

You might have to pull it and magnaflux the block.
I know this is a dumb question, but do you have a line from coolant steam plugs on head to radiator or a line from water pump to rad? That could be you over pressure coolant system if not, figured I'd throw it Out there
Good idea. It's gotta be something simple I would say. (I hope)

is it a line from the front coolant bypass crossover? or do you have it running straight from head?
Also i have seen excessive coolant pressure caused by a bad radiator cap...i know its simple but it DOES happen...
I always approach things with the KISS method, and then if that dont work i got to the more in depth reasons it could be acting up...
Good luck man, hope you get her fixed...
