Bottom end build
I'm looking for suggestions on shops to build my 4b11, I recently discovered all my cylinders are right around 90psi and cylinder 4 has 15+% leak by. I had the cylinders scoped aswell looks like 3 and 4 have some significant scoring. I live in the south eastern US. I had a local preformance shop look at it, they're asking roughly 11-12k in parts and labor. Is this reasonable? Is there a way to mitigate huge labor costs? I don't have the time or knowledge to do the build myself or the proper tooling for that matter. What are some of your experiences?

If you can't build it yourself, you're going to pay labor, simple as that. And trying to go cheap on an engine WILL cost you a lot more money in the long run when the engine eventually fails and the cut rate shop you chose doesn't behind their work.
11-12 is probably about in the ball park for a fully built and installed engine. Make sure you're getting a sleeved block. And make sure you're going with a reputable shop so you only have to spend the money once.

No I'm not going to buy another stock block. I'm thinking an overbore will be the way to go. At this point I'm not sure wether or not to go ahead and sleeve the block or just go with oversized pistons. And I'm also thinking the head will be built while the motor is out of the car.

I went through a full rebuild last year. A high quality build with lots of new parts, new valvetrain, cams and and a properly sleeved block will cost approx $8,500 with labor to assemble the short block and cylinder head individually but NOT to put both together with all the bits and deinstall/install in the car.
Like others have said, for a high end high quality build, expect $11-14k out/in.

So I'm assuming you cut some of your costs out by removing the motor and doing the install after handing it off to someone else to build? I was thinking that this might be a good idea. Who did you choose to sleeve your block? And did you use the same shop to machine your head aswell?

If you're taking you're car in for a "one stop shop" type of build, make sure you're taking it somewhere good and reputable, and let them spec everything out and use the machinist they usually use. That way if there is a problem, it's on them.
If you want to do it yourself, RED (Race Engine Development), or Golden Eagle MFG are great companies for sleeve install.

How did go about doing this? Did you pull the motor yourself and then ship your head and block to separate shops? Or did the same machine do both your block and head? Also who did the assenlmbly of your block and heads? Im interested to know because I'm thinking this will be my best options in terms of savings, also I feel fairly confident that I can pull the motor, at that point I would be scared to do anything else.
Then the shop I trust put everything back together. I also had him do the lash adjustment on the head with the new cams which came out great. (no valvetrain noise).
It is a two person shop so from dropping my car off to picking it back up took about a year. It was a bit frustrating time wise but the work was top notch. I requested the machine shop redo the bearing clearances on the block because they did it before I was able to request custom clearances so that added a month but over all it took A LONG TIME.
Prepare yourself. Also notice I put shop I *trust* many times on purpose.
