There are very good reasons NOT to do this. At idle with this much advance you will get decent idle. Try it on an engine some time with a hot cam in it. At the proper setting 12-15 degrees maximum it'll idle like a pig. Advance it to 25 and it'll idle beautifully.

However at idle you only have partial cylinder filling, nail the throttle to pull away hard and it will pink under load, you just can't hear it doing so because of all the other stuff going on. If you want this much advance idle you need mappable ignition, with a map to back it off to safe levels on hard acceleration. Or regular engine rebuilds. Equally advancing much above 39-40 degrees total is asking for trouble.
