Urgent Recommendations Needed for 4.0 Engine Rebuild

Where's the best place to go to get my motor rebuilt in the Phoenix area?
Are The Engine House, Arizona Engine Rebuilding, or The Engine Builders any good?

My daily driver needs some motor love. Head gaskets are toast and from the quotes I got to replace them I may as well just rebuild my 315k miles motor.

 

Seriously 315K... Respect!

Curious to hear what recommendations you get... My timing cover is going bad and needs re-sealing. I've heard some people fixing it from the outside but that seems like a bandaid an I'm not sure I wanna take on fixing it from the inside myself.

 

I ended up going to The Engine Builder in Glendale.
So far I have about 1500 miles on the rebuild with no problem.
