Ive got my stock 1990 dx head off for a head gasket replacement and i figured i would see if there is anything i can do to it while it is off. Also, what can I, or should I use to knock the build up off of the valves and pistons?

thanks!

 

Well They have some sites with directions on how to do your own port polish but i dont know if you want to do something that extreme or not--just clean it up
