Allan, I tried Mordy's gasket (a work of art), with limited success.  It 
is really critical that the sleeves protrude 0.002 - 0.003 (check his 
Web site for exact #, I'm going from memory) and that they all protrude 
equally all the way around.  If your engine meets those requirements, 
you won't be disappointed with his gasket. A side benefit is, since the 
gasket is thinner than the composite gaskets, you'll increase your CR a 
bit.  He can also make special Figure 8 gaskets to provide the correct 
sleeve protrusion.

I'm surprised you've burned gaskets with 87mm pistons, as I believe the 
new gaskets are all made to allow for 87 pistons.
