Refreshing an old post...regarding Stealth heads...

I did some initial measurements today. I just have home-made equipment and I wasn't sure I was going to be able to detect any differencies between the chambers.
- With my bare eyes I can see and feel differencies between the combustion chambers (at the edge of the quench area).
I tried to visually decide which is the smallest and biggest chambers by feeling the thickness of the edge at the quench area:
- one head measured between 78cc and 80cc
- the other head measured between 80cc and 82cc
These are preliminary results, I'll do more (and hopefully better) test to verify that this is actually the case.
The fact remains though that I can see and feel differencies between the chambers. It looks like core shift to me, some chambers are just a little deeper than the rest.
Anybody else seen similar things?
