These came out of my 1999 B18b head. I put these in when I had about 5,000 miles on the motor. I put about another 5,000 miles on the motor when I pulled the head. These have between 4,000 and 5,000 miles on them. Bought them new from Acura

You don't have to pull the head to install these. All you have to do is pull the cams. They are not held by a bar like a VTEC application

Asking $150.00
