You would never have enough clamping force on the liners to crush dead soft
copper fig of 8's appreciably. No, the liner gaskets need to be at the
appropriate thickness to raise the liners to the proper height. Naturally,
this measurement needs to be done under some load.
What I do is meticulously clean the the block liner perch and ensure the
liner pedestal is clean. -then fit the liner bare. Measure the liner
position relative to the deck. I use a simple but straight edge and use a
feeler gauge to get the clearance. Then make a determination as to the fig
of "8" gasket needed to get the liner to .005" in my racing motor. .003" is
not enough (me thinks). I make individual rings for each liner as needed.
I can't believe that figure of 8 gaskets still exist. I may have .012" on
one liner and .014" on its neighbor. Alternatively, I sometimes face off
the liner on a lathe to clean it up and use thicker rings as needed.
For the purpose of a sealant on the bottom of the liner to the block... use
a very thin coat of aviation gasket sealant, gascachinch, indian head
shellac... or some thin goop. You don't need much. At one time I used no
goop at all. I don't use yammabond, hylomar, silicone Rtv for this purpose
they will raise the liner a bit.
