Thank you for the info.  I ordered the FJ20 rods today, pistons next.  Slowly but surely... 
I have been messing with the engine calculator.  I assume it is correct...

So for the .030 inches of clearance, you are including the head gasket height correct?  This would be 0.762mm between the head and top of the piston.  So assuming I am using a 1mm gasket, I would shoot for about 0.24mm rise above the deck for the piston?
