Sadly, we won't be able to make it.
I just got the block back from the machine shop last Tuesday. Not enough
time to get everything together and in the car and ready to go by Thursday.
The good news is the liner stick out is the 0.004 the machine shop said they
machined the liner seats and deck to. It's still a bitch to measure, as the
liners "wobble" on the seats and when you're looking for 0.004 it's a
problem. I finally have a decent dial indicator gage setup to at least give
repeatable readings. The figure 8's used was a set of copper ones I had
that measured 0.016. The machining was done on a single setup on a Rottler
floor type vertical 4-inch spindle milling/boring machine. These are
special purpose machine tools built specifically to machine engine parts,
such as blocks and heads. After all the machining to get the stick out
right I now have the pistons sticking up about 0.010 above the tops of the
liners. No problem with the composite Payen head gasket.
Thanks for all the responses to the Figure 8 gasket question. I did
eventually hear back from Moss UK. They said their steel fig. 8's are 0.016
and their copper fig. 8's were 0.018. No explanation regarding the
different thickness other that they have not had reported problems with the
gaskets. I'm not sure where the 0.020 thick copper ones that I measured
came from or for that matter, the 0.016 thick copper ones I'm using.
