Yes, I know that most of the bolts are torque-to-yield and are supposed to be replaced after being taken apart, but my motor has to be redone (long story, not my fault, shop is supposed to be covering it) and since the engine was only together for 3 months, 1,000 miles there is a debate over whether the bolts "NEED" replacement.
Soo... I need to know the measurement specs for the:
1. Rod Bolts
2. Head Bolts
3. Crank Girdle Bolts
If anyone knows the specs on these I'd really appreciate it if you could post them for me, thanks.

BINGO!!!
Rod, most crank, and head bolts are all TTY.
Re-using will lead to failure due to loss of torque and even breakage.

It was not broke; Yet I fixed it anyway.

even if they were only together for five minutes, a TTY bolt needs to be replaced once it has been removed.

That's what I'm saying, but the counter arguement is that since the bolts are hardened steel and the block is aluminum there is no way the bolts stretched. There's no real debate about the rod bolts except they don't want to go through the hassle of replacing them, so they're saying it'd be fine to reuse them.

either way, there are no ifs ands or buts about it, TTY bolts need to be replaced once they've been used. If they didn't stretch before, then they didn't install them properly the first time. Torque to yield bolts are intended to stretch, BY DESIGN, when installed properly regardless of what they are being screwed into.
The steel vs. aluminum argument is retarded and I wouldn't even respond to it to give it validity.
I would insist this shop pay to have the engine redone elsewhere and never ever use them again. Re-using TTY bolts is a rookie/idiot mistake.
basically, if they do re-use the TTY bolts, they WILL be rebuilding the motor again. Though, they will probably come up with a better story about what failed first and try to get you to pay for it again.

What Rara said to the "T"
I bet these idiots would also argue that a ton of lead weighs more than a ton of feathers! 
2000 SVT Turbo 295hp/269ftlb@12psi
#1 for Bendix Brakes Kits!
Knuckles rebuilt w/new bearings $55
AUSSIE ENDLINKS $70
Gutted pre-cats $80/set
A lack of planning on your part does not constitute an emergency on mine!
