Mazda 2.3L

I am just trying to get some advice on here. I have a 2008 Mazda 5 2.3L with 178K miles on it that had the head gasket go bad. I have since replaced the gasket and 2k miles later it has started to show the signs of it going bad again.(overheating, coolant reservoir over flowing). My question is, should I take the head off and get it checked out and tested or should I just replace the engine with one of the 2.5L ford block?

That seems a bit low for compression. Sounds like its leaking compression into the cooling system if its making the coolant flow out of the overflow. Honestly if it blew the head gasket before and seems to be doing the same thing, its a good idea to just replace the motor.

2.5 swap is the way to go.

I can't recommend enough the 2.5L swap. Nearly every problem the catastrophic 2.3 engine had was solved with the 2.5L I currently own a 2010 3s with the 2.5L engine and it has 212k miles and runs like the day it rolled off the assembly line and it still kills new vehicles in little street races runs from light to light. All the oiling problems are gone as the oil system was redesigned and has many oil jets on the piston skirts as well as better oiling to main bearings. You can't kill this engine as I beat on mine like I stole it every time I drive and she just begs for more.
