Check my sig and my threads as well. Also there are some good threads if you search that will help you out.
Anyway use the B18a block. To get close to 12.5: compression get a set of CTR(PCT) Pistons. The pistons will have to machined to make them fit but they will work fine. This will put you between 12.2:1 and 12.4:1 CR. Next a set of ARP 8mm rod bolts and new bearings. You can use a block guard, it wouldnt hurt!
If you can find a B18b(P75) head instead of the B18a(PR4) you will start out with a lil bigger ports; but the B18a head will be fine if thats what you have. Get a PnP and a good valvejob. As for cams a lot of ppl use Crower 404's. With 12.5:1 Compression, 405's may be an option, but make sure to get the right ones or you maybe in trouble and have to modify the head to make them work!. Crane and Exospeed make some good cams too. Go with the vavletrain made for the cams you select.
As far as bolts go, this part is up to you and what you choose! Good Luck.

Your question was already answered. You can get right around 12.5 with CTR pistons in an LS block w/LS head.
CTR pistons do come in 81.25, I have them in my block.
Try searching a bit more.
BTW, why are you set on 12.5 CR? Are you going to be daily driving this car? How will it be tuned? What octane do you have available?
CTR piston have a ZERO piston to deck height in an LS block. I would seriously suggest claying your motor NO MATTER WHAT cam you go with.
No offense, but you have a lot of research to do. Save yourself some money in the long run and learn as much as you can before you attempt this build.

You do not need to bore! Check my sig and click on my "Dyno and Setup". I put down 170 WHP and 135 WTQ with Crower 404's and P30 Pistons!

Yup, you can get a hell of a lot more than 145 whp out of a stock bore b18a/b.
Digga4, you would make much more power with bigger cams and more compression. How much was your head milled? You probably aren't even at 10:1 CR.
