Here are the compression heights of pistons in question:

Stock 1969 piston: 1.77 info source "How to Hot Rod Small Block Mopars" by Larry Shepard
Sealed power 285AP30: 1.720 info source Summit Racing
Mahle S224-2007.030: 1.741 info source Summit Racing
KB167.030: 1.810 info source Summit Racing

As already stated Mother Mopar was very liberal in "claimed" compression ratios. There is more to compression ratio than what pistons to use; just proceed carefully.
