The block surfaces still have marks on them from the head gasket, but I only cared about getting the dirt off of them. They are smooth to the touch and so is the top of the cylinder where the carbon builds up. I was careful not to scratch that head gasket surface.
I haven't touched the heads since removing them. I will clean them up as soon as my valve spring compressor tool and HR valve springs, HR head gaskets, shims, and seals arrive.

Wiring? I haven't come close to that part of the project yet. Step 1 is to get this engine together on the stand. Then I'll physically install it in the engine bay with the 4th gen crossmember. Then I'll worry about installing the wiring harness.
I already have a dash harness. And I already ordered the engine harness, but it got lost in transit! They claimed they have found it, but I can tell they don't know for sure. I know the package is insured, but it's just a hard part to find, I don't want my money back. I want the harness!
In the meantime, I can go through the harnesses, label and prune out what I don't need like eng92 did.
Yeah. And I don't want to scratch up the top of the pistons. Did you get my PM?

it's a simple multipole DC motor with a worm gear on the end, hooked to a set of reduction gears, then the mileage tumblers. +12v and it counts forward. -12v and it counts backward. theoretically...

looking good, Aaron! So you're pretty much done with the block then? now just onto the heads and stuff... as long as you get that engine harness everything looks to be going smoothly.

I still have to remove the upper oil pan, install ARP bolts, and clean off all the old RTV on the pans and timing covers. Then I can concentrate on tearing down the heads.

Looking at photos, I think you could drive them inwards.

Edit: I just tried it. They came out really easily with a punch and hammer. Thanks.

Just got this handy little tool from Snap-on today for $35! It's the fastest and easiest way to remove and install valve springs and keepers. All you do is push on it really hard and the keepers pop out and attach to the magnet. To install, just load the keepers in the retainers and push really hard. If you're not strong enough, you can just hit it with a large hammer.
With this tool, you can change all the valve springs on the head in less than 10 minutes.

Here's the link. The 350z guys love this tool. And after using it, I can see why it's nice to have.

All I did was remove one stock valve spring and reinstall it to find out how well it works. I probably won't receive my package from Dave B until the end of this week. It will have my new HR valve springs, HR shims, HR head gaskets, HR head bolts, orings, valve cover, VC gaskets, exhaust manifold gaskets, CVTC gaskets, and other seals.

The mileage is displayed digitally on a LCD, and that data is not reversible.
I think the OP is using the 5.5 Gen cluster.

And no, there's no problem with that. Go for it!
