After almost a year hiatus working on my RV-9A due to a family member illness, I am back in the hanger working on my RV-9A project. I am the third owner of this quick build kit which came with a new Mattituck IO-320 Red & Gold engine manufactured in September of 2005. It has 1 hour of test stand running time in the log book.
I finally got around to identifying my cylinders. All cylinders are AEL65102 with cylinder heads P/N AEL85099 and fall under the FAA AD.
After a lot of head splitting research, I have not been able to POSITIVELY identify the serial number location(s) to find out whether they fall under Part A, or Part B cylinder compliance. The ECi web site is now gone of course. Here are a couple photos of where I am almost positive they are located, and the two I can read would place them under Part A cylinders.

If this is the only location of the serial numbers,, I will obviously have to remove two cylinders to get all four SN's.
1. Is there another location for the serial numbers other than the location circled in the photo?
2. If not, can I assume the other two cylinders will have serial numbers that fall in the group A cylinders? The two I can read are #2- SN: 30677 29, and #3- SN: 31828 04. The engine log book does not have the serial numbers recorded, and I am leaning on pulling the two cylinders to verify and record the serial numbers in the engine log book.
3. Are the majority of people flying with the group A cylinders comfortable and confident flying behind them and complying with the every 50 hour inspection procedure, or just replacing them with new cylinder assemblies?
4. If I do replace all 4 with new, is there a market for the old Part A cylinders to help offset the costs?
Thanks for any help or guidance.
