Default Z6 rebuild questions

Don't worry, the z6 isn't for me . I'm pretty set on an ls swap I think. My friend is going to buy a z6 in the next few weeks to rebuild for the summer. As of right now he doesn't have anything to put it in, he has a winter truck but will be buying either a shell or a high mile/blown motor hatch to drop it in. So until spring/summer I am going to help him tear down the motor and rebuild it and get everything good as new. It'll be a good way for him us to get mroe familiar with the inside of the motors, give me a base for when I build up the ls in summer. He doesn't want to build it up, just wants it good as new. Somehow he says he will be satisfied with the z6 in the hatch, I don't think that'll last long once mine is swapped. But anywho, my question is what all should we end up replacing/refurbishing.

This is the base plan so far:
-Timing belt
-Water pump
-ARP head studs
-ARP rod bolts
-Performance rod bearings
-3 angle valve job
-Clean everything up with parts cleaner
-Might as well do piston rings while everythings off
-Head gasket/valve gasket
-Probably do valve seals too

Am I missing anything else we should just do right away? Like I said he doesn't want to build this up, doesn't have a ton of money nor the push to do it. (He's one of those kids where if you give him too quick of a Civic he will put it around the tree showing it off too many times) so it is a good thing we aren't building it, even though it's a d. But in an ef hatch it should pull pretty hard. Thanks for the help.

oil pump
yes do the pistons rings and valve seals
rear and front main crank seals
cam seal
inspect the cyl walls, may need to be honed a little since you are putting new rings
and what you listed and you should have pretty much a new motor.

Should we even get the arp headstuds? I'm just thinking that it might be an unneccesary $100 seeing as we aren't building the motor, and it would save a good chunk of money for other parts, same with connecting rod bolts.

i say you can re use the old head studs and be ok, same as the rod bolts. just torque them down a little more then spec.

Alright since it's not a huge performance build I figured we could save the money, don't want this to be a like $300+ rebuild lol

Alright I'm on eBay getting estimate prices on parts for the rebuild and I have a question on the rod bearings. I found this: http://cgi.ebay.com/ebaymotors/ACL-R...Q5fAccessories and my question is that all I need...? Because there's also these packages: http://cgi.ebay.com/ebaymotors/ACL-R...Q5fAccessories and that one comes with 4 pairs of bearings, one set of main, and a pair of thrust washers. So does the 1st one just give the 4 pairs of bearings? I'm kind of lost on these, and is the 2nd package thingy necesary? A little pricey .

i suggest stopping by a local auto part store and getting prices first, then compare it to ebay, because if you get a wrong part at the part store you can easily take it back, but on ebay you get what you pay for. also the part store will be able to explain to you.

the first link is just for all four rod bearings and thats it, each piston rod gets 2 sleeves, thats why they say 4 pairs.

the second link is a complete crank bearing kit, it has the rod bearings for all 4,and main bearing reason its pricey is because its performance kit.

I just went to eBay to get guesstimates, anything I can get at Napa I'll get there. Napa is awesome with parts.

So do you suggest getting the complete crank kit? Or would just replacing the rod bearings be fine.
