Toysrme, spot on! 
My experience with 3VZE engines was positive. 4.10 axels, 31 inch tires, manual locking hubs and a decent low flow muffler make the world of difference in performance.
With the addition to Toysrme suggests you can make a moderate amount of horse power and torque without sacrafising reliability. Not every block can be welded.
But, Toyota uses more nickel in their's creating a stronger block.

As always, what I say doesn't seem to apply with 3vz-e's, but that looks like crap across the board, not just 1 dead cylinder. Nearly every Toyota economy engine of the 80s-90s has 142psi minimum, 178 psi normal. No more than 14psi difference between high & low. (Anything more than 14 indicates a problem brewing)
That being said, I'm fairly sure the 3vz-e falls into the 178psi normal, 140psi min.
As a side note, on this 3vz-fe the last time I had a blown HG & torqued the SOB down to 100ft-lb, compression rose out of spec to 185 psi.

the motor is toast.
I think the heads are fine, that most fo the problem is with the rings. IIRC the heads were replaced under the head gasket recall work.
However, I am debating throwing the 3VZ ot the wind and putting in a 5VZ.
Just trying to make up my mind.
I can get a 5VZ block (that needs to be rebuilt) for around $200. That includes the 5VZ wiring harness and a few other items.
I am thinking about having that one rebuilt and set up for forced induction.
On the other hand, I wouldn't mind having a truck that is totally stock.

Well, if you're looking for a 5vz that is set up for forced induction, it really depends on how much boost you want to run. The internals of the engine are quite good for running boost, it's the fuel system that needs to be upgraded for forced induction.
For $200, I'd definitely ponder the swap. I guess it really comes down to how much you really need to use your runner. Plan on it taking time.
