how hard is it 2 change a head gasket on a b16a in a 91crx si?

 

Well not that hard, it is a matter of disconnecting and draining everything that is the bitch. If it is just a routine change, i.e. the last one didn't blow, IMO 4-5 hours if it is your first time MAX barring any of Murphy's Law from striking. This is after the 3 hour cool down period of course but for all I know you could do it much quicker and call it a day Oh, and get a friend

 

any 1 else.....any links for "play by play" instructions...?

 

well look at a service manual, even a haynes will be sufficient.
