Blown Head Gasket repair w/pics

(From my thread http://www.toyota-supra.info/forums/...-problems.html)

Hey everyone,

I bought my 88 Supra Turbo with a BHG a while back, and have since done the following to it:

New HG and upper gasket set
ARP Bolts (70ft/lb)
Different turbo head purchased (old was warped .020")
Head machined flat, checked, and valves reseated
Set of completely refurbished fuel injectors (ultrasonically cleaned and flow tested)
Vacuum systed completely gone through and everything is properly connected.
Also tested every coil pack for spark (looked for spark in a removed plug attached to each coil pack)

Feels like a cylinder or two isn't firing.
Here's a video (don't mind the squeak, alternator belt is not tensioned all the way)

The car starts but runs terribly, once the RPMs go past 2500, all power is lost until it drops below that.
If you keep the accelerator floored, it will go up past 2500 RPMS, then fall back to it over and over.

Can someone help me?
I want to get this thing on the road!
