Default possible blown head gasket but still good compression?

Car was having very tough time accelerating lots of hesitation, probably due to the spark plugs being soaked. One in coolant (nearest to dizzy, the others I'm assuming just oil and unburnt fuel. Did compression test, and 180-190 all across the board (wet), steady.

Is it at all possible to achieve those numbers with a blown headgasket? IS the only other place the coolant could be coming from is the coolant port going to intake manifold?

first pic is the coolant one, others is what I believe to be just oil/gas

Have you drained some of your oil to see if it is frothy and white? That would for sure tell you it's head gasket.
It COULD be valve cover gasket, check that.
Fix the cheap first

If your getting good compression I can't see how it could be a head gasket failure. Just in case check your oil for milkiness and radiator for bubbles.

Do a leakdown test. It's the only way to know for sure. If you don't have a leakdown tester, simply pump about 35 psi of air into each cylinder when it's at TDC (all valves shut for that cyl) and see if you're getting bubbles coming up in the radiator or coolant overflow tank.

We've had engines w/ blown headgaskets give fairly good compression readings and be mixing like crazy - just like what you have. That is DEFINITELY a blown headgasket (or a cracked head).

Leakdown test would have shown this.
