i just took apart a b20 i am gonna swap in my 93 civic hatch in order to do the headgasket and arps and i had a quick question. the block was fairly clean and i barely had to scrape any residue from the headgasket off, but i didnt take out the oil control orifice and clean it. right now i just have the head sitting on block and headgasket, through the headstuds and i haven't torqued anything down.

should i take the head off and clean the oil control orifice or should i be ok? and how do i take it off? the manual doesnt show how? does it just pop out? or do i have to thread it out somehow?

thanks in advance, and sorry if its in the wrong seciton.
