Alright, so my setup is for forced induction, but I know everyone in here would know this much better, and its a motor building question.
I am using a 81.5mm block, with LS crank rods and pistons. I would prefer to use all OEM bearings, but want to check which ones to order. I may just have my machinist measure it all and then order based upon bearings, but thought I would ask first. My questions are:
1) For the main bearings, Do I use the block code or what is on the crankshaft? Also will these be GSR or LS bearings?
2) Which thrust bearings should I use?
3) For the rod bearings, I am using eagle rods- should I follow the guide on the crank? Or is this something that I have to mess around trying different bearings?
Also I have compiled a spreadsheet with everything that I need to order I feel- Would anyone mind looking this over and telling me if anything is wrong, missing or unnecessary?

Would the 81mm head gasket be fine even though im at 81.5mm bore?
Thanks in advance!

Answers to your questions:
1) For the mains, you can use the codes from the block and crank to determine sizes. OEM B18/B18CXXX/B16 are the same bearings.
2) OEM
3) Non-OEM rods will require measuring both the crank journal and big end tunnel race before you can decide on the bearing. If ACL will give the proper clearance then use them else you can mod the rods to accept OEM GSR/ITR bearings.
4) Stock headgasket will be fine.

Thanks for your help.
Any takers on what else I may need for the rebuild? So I can just order thrust bearings for a gsr and those will be correct even though its a ls crank in a gsr motor? thanks!!

Yes, this is known. Read his post. His question was about the mains.

Save yourself some cash by buying the cylinder head gasket kit for what ever head you are using. Comes with everything on the top of your list up to and including the headgasket. Also intake and exhaust manifold gaskets.
not sure mar778c..... all i know is i want coated bearings for my build but i cant find anything on their site that specifies anything for an early year h22 as far as acl goes. i just had my oil pump go out on me and im rebuilding my entire block so i want the best parts for this build.
