Thanks for the info Ian. I've never taken all of the plugs out first. I always do one at a time with WOT to get my compression numbers.

I'm interested in the new numbers as well since I've never heard of one being higher than 180ish.

AFAIK the way you measure the deck height is from oil pan part of the block to the deck. To get such a precise meurement to render an accurate reading you need to measure through a cylinder with piston/rod missing.

Cant exactly eyeball this measurement with a craftsman tape measure...

From memory an uncut block is 198.5mm from the Deck to the Crank Tunnel.

Use toyota FIPG ( RTV) in those location ( Badass stuff). Make sure you straight edge the block for warpage too prior to putting the head on. While the head is off replace the EGR cooler gasket (toyota gasket only)( if you plan on running the EGR system). Torque accordlying to TSRM at 80 FT lbs trq as the last sequence. IJ is a very knowledgeable person as are many other members on here too. Help is only a question away.

Remember to ask for all your old parts that was replaced. In this case you know they did replace them. My machinist was very honest and I got my head fully reworked for about 575.00. Always ask questions... (leak test, repair any cracks, bake the head if needed) ask them to check everything and make sure they are in spec. I ended replacing 5 valve guides, all valve stem seals, 1 exhaust valve, valve springs with new retainers... blah blah blah. Take your time... you will be happy with the end results.
