High Knock in my Talon

[Halon]

OK WTF!! I took the head off, everything looks to be absolutely fine. I mean I suppose there could be something really minor in there, but I'd think if it's something so small that I can't see it that I'd still get a little bit of compression, like 25 or something. I'm getting straight up 0, and the head looks to be perfectly fine. Pistons look great, you can tell I just did the MCCC cleaning on them! I guess I'll get the head pressure tested atleast while it's out just to be sure, but jeez this is just retarded.

Oh and the headgasket looked fine as well.
