i have a b18c1 motor that i need to replace the valve stem seals on. i am wanting to replace them with the head on the motor. do i have to remove the cam shafts so i can lift up the rockers to pull out the valve springs? i am thinking about doing this soon so any advice would be great
(i posted this on TI as well but lately i have not been feeling the love there so you all want to be my friend )

 

Yes.
