Hey i bought an ls head from this guy off craigslist and he told me its an obd2 and it came off a 98 integra. Im just curious if there is a code on the head somewhere that tells you the obd, on the intake side of the head it says P75 and when i searched google it told me obd1.

 

If it came out of a 98, and if it came with the car, I would think OBD2. If that was swapped, could be anything. What kind of engine did he say it came from? B18b1?

 

he didnt tell me what motor it came off of, i would assume a b18b1 though

 

there are stamps on the head where the exhaust ports are, it will say the head stamp and also what year it was made.
