I have been questioning whether or not i think this would be money well spent?

interesting article. The link is for their break-in oil which contains high levels of zinc as landtank mentioned is an important component for initial start-up.
I can't seem to find any other motor oil specific for start-up break-in.

Joe Gibbs racing has a couple oils for break-in that were recommended to me by my machinist.
In the end, Dr. Robbie stated that a decent heavy duty diesel oil, non-syn, would be adequate since I wasn't technically breaking in the cams.
Still on that for another 100 or so before the first 1000 mile oil change.

Thanks!! Dr. Robbie is a good source of info IMHO!
Sounds like a diesel motor oil it will be.
Now off to mic some shims....
I've got a draw full of shims so let me know what you need. I won't be able to get them out to you until Friday afternoon at the earliest. I just ask that you send back what you take out for the next guy.

Valve Adjusting 101
The 1fz is a little different to other motors in the aspect that the cams lobes mash on a upside-down bucket with a shim on the lid. So if you have clearances out of tolerance, you replace the shims with a different size.
As you can see all the shims sitting there. I have already taken measurements with the cam in place and then pulled the cams to get to the shims.

I think it's important to keep a good written record of what you are doing. So i literally drew myself a picture of the head and the valves, number them and put their measurements beside them.
With this knowledge, i used a magnet and pulled one of the opposing valve-spring buckets.
then popped the shim out of the top of the bucket as you can see. You need to do this so you can measure the shim that's in place with a micrometer and know where your baseline is.

So then you flip to the page in your FSM that has this nifty chart! 
Here is where i would like to confirm with others that i'm reading this chart properly.
In my case, i had a valve clearance measurement of .008 inches. On the left side of the chart they have "Measured Clearance" in mm and in. moving on the y axis. Then you take the measurement of the shim you have in place; mine is .1122 in. and find that on the X axis at the top. You then intersect the two lines, and, i come up with me needing to replace my existing shim with a #6 shim which measures .1083 in.
Please correct me if i'm wrong with that?!
This same process should work with the clearances that are loose also, right?

sounds right, that'll give you .012 clearance

Can you replace the shims with the cam installed? Shim above bucket style lifters typically allow you to change the shim providing you compress the valve springs. My old Honda motorcycle used a semi-circular tool that pressed the edge of the bucket down so you could retrieve the shims. Of course getting the correct tool for depressing the springs is probably a different issue.
You may want to invest in an outside micrometer. Typically they're used for this application. Although yours is probably good enough.

Yes you can. It calls for a SST to do it, and i'm sure there are those out there who have rigged something up. BUt for me right now, and wanting to learn, i decided to do it the long way.
I didn't use the chart. I measured all the tolerances, then measured all the shims, then calculated what each valve needed for shim thickness. That way I could move a few around to save on ordering so many of them. Once that was done I took the final list and used the shim thickness chart to order what I needed.

had to go get some more gaskets today that were not in the gasket kit.
1 Thermostat Gasket ------- 16119-66020
1 Thermostat Gasket ------- 16346-66020
And i needed a thermostat ----- 90916-03117

You should start a thread called "Gaskets not in the gasket kit." I would have lost it by now. Does the gasket kit actually have any gaskets in it?

I may be able to do that in some cases. I'm thinking that the tight valve shim may be replaced by one of the loose valve shims. This could take a little time

lol... there have been a few times i've had steam coming out of my ears since i've had to stop wrenching to go order new gaskets. The last few are not critical at this time as i can play with the valves while i wait on these, but others not so much.
I hope that maybe cdan can take this thread and the next person that's doing an overhaul can order the gasket kit PLUS all the missing gaskets that i've identified here.

Do you guys think that when this motor was originally built at the factory they had more valve shims than they offer as replacements? I'm asking because there are a lot more size options in the chart than they offer replacements; and, some of the one's i have taken out and measured were not a size in the replacement chart.
Or, i need to get a second set of micrometers to check my original measurement.

started turning wrenches today, and i know this is going to throw you guys off, but, i'm missing another gasket 
Missing the gasket for this coolant passage tube that goes on top of the thermostat housing that also didn't have the gasket.
EDIT: that gasket IS in the gasket kit! I had misplaced it!

that gasket does come in the kit. Look around for it.
