I was on ebay the other day and found a itr head with upgraded camshafts and valves and was from honda of japan goin for 7 hundred. Seemed pretty cheap to me. Anyway how much would a head be for the itr ? Looking to buy a head and slap in on the B20. I'll probably be able to pick up the head in dec. so if anyone knows where to get one then please send me a thread.
