i know what yall are telling me. but i still want to know what the head originaly was cuz if i decide to sell it i need to beable to tell them what it is. you can sell a b16 for around $300 and an itr for around $400 just cuz of the name. the green paint is gone if it was there in the first place, and the head has been p and p by previous owner. i was told i could tell by the date stamps but i dont understand what they mean. so if anyone can just let me know if its itr or b16 or b17 cuz all of them are pr3-whatever, i would greatly apreciate it. thanks
