I think I figured out my coolant leak, please confirm

[kinder]

So after reading everything I could find on the site about coolant leaks I think I've got it figured out, just need a little sanity check. All this time I thought it was my intake manifold gasket b/c it had a small leak out of the front of the manifold when I picked the engine up, but I should have tried to run it first before changing the gasket and I think I would have taken a different path. So to recap the symptoms: coolant out the exhaust at the tip on driver's side and leaking at the header flange, coolant in the oil and coolant fouled plugs on # 6 & 7. I've replaced the damn intake three times and I wasn't going down that road again. So I thought back and racked my brain for other symptoms...like: the radiator seemed to have too much pressure when I tightened the cap, bubbles would rush into the overflow, and looked closer at my existing problems, like # 6 & 7 cylinders. Wouldn't a intake gasket leak foul # 5 & 8 first? So off to the store to pick up a coolant pressure test kit and set the # 6 cylinder to TDC, pulled the plug and put the pressure on. And wouldn't you know it coolant ran out of the sparkplug hole!

So after all this it has to be the head gasket or a crack in the block or head right?

Thanks for letting me rant.

Yep. Pull the head and see. Probably just the gasket.

Cracked block or The head could be warped. No matter how many gaskets you put in if the heads warped its going to leak.
