questions on air conditioning?

I emptied my freon about a month ago, (was taking off heads to be ported, and new cam shaft), Now I put the original cobras on for the time being; recharged the system and now it wont work??? I have plenty of pressure, No leaks (checked with thermal glasses, and my compressor is turning??? WTF its getting hot here and I want my air. please help.
 
I dunno if this has to do with anything but im trying to put my a/c back in and apparently the dryer gets hunid if oyu drain it for the period of time. $70 for a new one :( . How do you just drain it and then recharge it? Are you paing $80 everytime you want it filled again?

Wanna sell your stock heads?
 
I'm giving my stocks heads rockers and push rods to a kid next door to me, he's 18 and building a 5.0 ranger for off road. He has little or basically no money so i'm giving them to him. Also I just bought a dryer for mine and it was $25.00????
