There has been some discussion here regarding head stamp. Many people have said the the first number is a 3. I had three individuals look at my heads and also used a magnifying glass (moving up in years ya know) and it is diffently an 8. One person on the board indicated that they were good heads. This determination is beyond my knowledge. Just as a note, I've been running 91 octaine and plan on doing that as long as I can find it. I run it in all my Harley's so I'm used to buying it.
