So I did my original test with the engine cold ... which I've learned was incorrect. I did a re-test again tonight at normal operating temps. Results were as follows:

cyl #1 - 230
cyl #2 - 230
cyl #3 - 230
cyl #4 - 230

Looks like everything is normal. *shrug* Anyone who reads this, learn from my mistake ... do your compression test with a warm engine. Thanks to those of you that offered advice.
