Anyone with a valve spring compressor i can use with the head on for rent

If you cant find one (I had a hard time finding one to rent or buy cheaply back home) get a big ass C clamp and an open ended wrench that goes over the retainer, but doesnt get in the way and jimmy with it until you can get your shit out (I think 15mm was the money size for me). Its pretty ghetto, takes some finesse, and is pretty time consuming, but if you need to get your shit undone and you are cheap like me, it works.
