30 lbs torque over another good spacer is worth it IMO.

Just relating to what a generic one inch spacer is worth for hp on the OP engine combination. I agree with your post though..some spacers are worth a little more hp or torque..but I struggle to accept "marketing" dyno tests. Each engine combination will respond differently as well a given hp increase on one engine combination will not necessarily be an increase on another.
