Project RX: I'm about to cry

At first it needed a new hone and new rings. Now, after taking it apart, it needs machining done to the crank. 2 pistons, as 2 of them are shot.
Where do I find new pistons?
Where do I find aftermarket larger main bearings? Because material will definately need to be removed there.
I'm getting very tired of pouring money into this. I'm already over the $300 mark. Thats without any maching done! Or accounting for the full gasket set I purchased or the new main and con. rod bearings!
How does a stock block have 2 bad pistons? This clearly shows to me the stock pistons are ****.
I'm starting to think of 2 letters. E. J.

Bearing speed is less w/an undersized crank.

I guess when your upping the boost, any bad spots in the cyl walls is going to leak, leading to lots of problems. I dont know how thick the walls are, meaning if you decide to bore it out any there might be some issues with that. Re-sleeving is an option, but I dont have any idea what that would run, and that involves a complete rebuild.
I hate to say it buddy, but I'm learning from your mistakes

For some reason, the heads I put on cracked also in the exhaust ports. They both already had slight cracks between the valves.
This time I decided to tear it all the way down, and do it from the ground up. I wasn't anticipating needing new pistons, so I was slightly surprised when the machinist told me 2 were bad (even though they all looked fine to me). I'll be dropping the crank off there tomorrow to get it measured, and see what can be done with it. I'll also find out exactly what is bad with those pistons. The crank doesn't look in bad shape at all. Each bearing surface though (mains) has a ever so slight groove in it. Barely enough to catch with a sharp tip of a knife blade.
If it comes down to buying a new set of pistons, I may ended up going ahead and boring it out a bit. Machine shop said 20 over wouldn't be a problem, and is what they've done in the past. Althought i'm not likely to go that far.
It will be $125 for honing and decking of the block. Looks like $200 for a set of OEM pistons. Will call tomorrow and see if I can get oversized ones from the dealer aswell.
I'm going to ask the machine shop if just 2 of the pistons can be replaced. I know this depends on what kind of piston I get. But that would prove to be a economical solution.
I'd already budgeted $180 to have the engine balanced, although before the machinist spotted the bad pistons, he had me talked out of it.
Monster in the making... Just a long slow exspensive road.
Caleb: I appreciate your offer, I will keep it in mind.
Turbone: I'm glad all this trouble is good for something! I want to hear that black beast purrin' like a kitten. Right before I blast the doors off of it.
Sorry, can't help but be cocky, its the one thing that will keep me going! That and the wonderful friends I have here.
