1HZ head tolerances

[proffittscruisers]

I have a 1HZ head that is a little warped. Toyota book says I can take .008 off and that is plenty for what I need. However, this head looks like it may have been machined before. Is there any other measurements I can take, just to make sure?


Any help is greatly appreciated.

Hmm,
my Toyota engine repair manual for the 1PZ, 1HZ and 1 HD-T engine states nothing about machining.
It just says a warp of 0.2mm (0.007873992 inch) is acceptable.
If the warp is more than 0.2mm --> replace the head !!!

machine it and the compression is going to be nuts...
maybe run thicker head gasket to compensate.
