Brighton - Wow, 8 thou is a lot- I am not surprised that the cam was binding!

Henry- thank you for the professional approach to this.

I have one group of heads that vary .0001" from tallest to shortest.

The other group of heads has one head that is .0012" taller than the shortest head. The other two heads in this group are within .0003"

So, I have one outlier........

I mic'd the heads at 4 corners and took the average. I am going to measure the second group again to check my measurements- after my crazy cc'ing debacle, I realize that I need to be very careful with my technique, when dealing with such small tolerances/measurements. That said, I may need to have one thousandth taken off of the top side on that tallest head.

I finally have all of my chambers within 0.5cc, so I don't want to shave the chamber side of the head.

All of this is me just measuring the "thickness" of the heads. I still haven't placed the cylinders on the spigots and measured the stack all the way up to the cam tower. We'll see where I'm at when I start stacking things and pull out the machinist straight-edge!

I really appreciate the informative responses & advice- thank you! (I couldn't find anything in Wayne's book or the Bentley manual)

Considering all of the work that goes into doing this the right way, I am curious as to what the budget Porsche engine rebuild house(s) do- just skip it??
