Dangers of cylinder head machining
I am building a 3.6 track motor. Started life as a 1993 964. I would like to raise the compression as it is less than I had expected but that partly is due to the flycut work on the valve pockets. I would do this by cutting the cylinder heads. I have dealt with issues with the earlier 3.0 and 3.2 engines in dealing with the resulting chain slack due to the decking of the cylinder heads, but not with the 3.6 setup. Wondering what I can get away with as was wanting take out .030''. I appreciate all advice. Bob
