Default Help diagnosing dead #5 cylinder

Hi all, newbie here.
I've been fighting with a friend's 95 Ranger V6 for a few weeks now. I think I've resolved all the problems but one. Here's what we've done:
-new crank sensor
- new cam synchro & sensor (it was definitely torn up)
- new plugs/wires
- new timing set (took front cover off, on the outside chance the chain had jumped, went ahead and changed it while it was off - 180k miles)

The engine has a dead miss on #5. It is blowing raw gas and what appears to be a lot of water and white smoke out the pipe. There's spark, gas and compression (120 psi) but no fire. My theory is that he's getting water into the cyl, that is quenching the combustion.

But, the oil looks good. Also, since compression is good, wondering about likelihood of BHG. The coolant also looked reasonably good. Does this engine have potential for water to enter from a bad intake gasket? Anybody have any similar experience with this motor? I just hate to bust into the head job without confirmation.

Any ideas for a 100% accurate way to test for head or intake gasket or cracks? Thanks for any wisdom.
