Hey guys I found something on my B18b1 head as I was cleaning it today. I’m waiting on parts and it’s storming here in Florida so this is as close as I can get to my baby LOL. Anyways I’ve searched and only found one thread in all of existence for this topic. On the exhaust side just above the ports and in between the 2nd and 3rd bolt I found 3 boxes with what looks like Japanese writing. All I know about this head is it’s from a B18b1 and it’s going in my 88 EF Sedan. If any of y’all have any info the. The other post a guy said he’s seen it all the time but every one else didn’t know really. If y’all know what any of it means let us know.
