Default First borescope inspection VA-400

I received my Oasis Scientific VA-400 borescope today, and was excited to try it out on my 75hr IO-360. I must say for $200 on ebay it seems to be quite the buy!

Both fuel and ignition is controlled with SDS EFI, and I've been doing plenty of experimenting with running ROP, LOP, different timing curves, as well as burning both 100LL and 91 mogas.

I plan on regularly scoping the cylinders to build history as the hours on my engine increase. That aside, this is the first engine I've scoped. I've red some basic info on what to look for, but open to any knowledge out there.

How am I looking?

Thanks for sharing Caleb. I also purchased a borascope for my RV and would like to know more about folks experiences using them.
