either pistons that have less dish, no dish or pop ups will raise compression.  Without changing heads, shaving the heads and zero decking the block can only give you a small increase, but make it necessary to alter the intake to fit with the changes.

Of course a turbo or supercharge will sort of raise the compression too!
