Hi, here it is:
Machine shop remove .1mm from my head and i remove .05mm of the block from lapping it. So i should need a 1.5-1.6mm thick headgasket. The fact is that i already have a brand new 1.9mm thick cometic headgasket in stock.
Is there a problem if i use it?
I know it will lower the compression, but does it will lower it enough to be a problem or i should not worry about it?
Thanks to let me know!

Don't quote me but stock headgasket is 1.37 mm compressed I thought. Since you took off .6mm and you have a 1.9mm hg that should keep you right around stock compression.

It will not really change anything to use that 1.9mm. Toyota has used at least 3 different oem thickness head gaskets over the years.

Lower compression will just have slower low end. Run more boost and the top end will be great.
