All the better! Less work on non-essential tasks. Thanks for being so detailed in your build! I'm going through the exact same part of my build w/ the head work and water / oil pump installation this week.

My boy @ work has been stressing this for the past two weeks. Now when you say new, you mean brand spanking new, or used lower mileage? My old one had 240k on it so it definitely has to go.

Your project is looking great, but I have a couple questions.
First, did you check for wrist pin movement before reusing your pistons? When I rebuilt my 2JZ, most of the pistons were worn beyond the service limit. The way to tell is to try to move the wrist pin within the piston at room temp. If it moves within the piston, the piston needs to be replaced. The wrist pins should be an interference fit at room temp and require piston heating to install.
Regarding your valve clearances, they are likely tight due to the valve job. Even though the stems were machined, they are probably still slightly high due to cutting the seats and grinding the valves.

Talking about pulling the engine out of the car again and taking everything apart.
I would not trust a used one unless you brought it new and ran it yourself. Most of these engines have been sitting for a while.
$160 at Elmhurst and you are good to go.

And as for the valve clearance, I have to go thinner shims. Yes I believe it was the valve job. I bought 20 shims and they are $7 per piece. Holy %&^!!

I like the look of chrome under any hood, when done properly and in moderation. I think chrome just says clean and clean means time well spent under the hood and done right. Jmo.
