Agree, learn how to read the plugs.
A Air/Fuel meter can get you close but Air/Fuel meters have been known to get contaminated and give false numbers too.
Spark Plugs do not lie (if you can learn how to read them properly).
27 degees of timing is like knowing where the edge of the cliff is. One more step and you fall off or in a engine's case take out a head gasket or have other issues. This is not a Chebby that needs 40 degrees of timing to run right.
One additional degree MAY GET YOU A FEW MORE HP OR IT MIGHT GET YOU A LOT MORE ENGINE WORK. Conservative on timing. Just saying.

Some actually cut the plugs apart and look deep inside them.
