1FZFE Stock Camshaft questions

[hazard]

Hi All
Doing a diagnostic 1FZFE teardown in preparation for a full and proper blueprint. Have done a bit already as you will see on my thread. Just finished detailed valve lash comparisons.

1FZ engine building and blueprinting

During teardown I want to map all specs on this engine against factory spec, I am doing this for fun as I am an anal perfectionist. So far I have two problems looking for help on:

1. No one seems to know factory camshaft specs, (on this form or others) so even if I measure and map out what's in there I won't know how they compare to stock, or if timing is right etc. Please help. I will measure and post results but it is somewhat meaningless without a comparison.
Anyone got the specs?

2. I am prepared to start measuring, and I can mic/dial the lobes for lift, but in order to map all specs I need to be able to measure valve lift/timing with a dial indicator. I have done this on regular rocker arm engines, but I can see no way of getting my indicator to sit on valve shim to take these measurements on the 1FZ. There just is no room as the lobe covers it. See pic.

Any good suggestions?

Figured out #2.
I an indicator, or indicator attachment, with a curved or L shape arm.
Any other ways?

I don't if this helps. But see page 5 of the pdf.

Thanks Atwalz.
However I am looking for stock spec and even their mildest is larger than stock. A quick measure shows 0.330 on stock intake lobe lift, although I have to re measure to be sure. Crower and others I have found are always 0.400 or more.
