How do i change a head gasket on an '85 monte carlo ss with a 305?

i know the basic theory behind it. take off the carb, intake, heads etc, replace gasket, put back together. what i need to know is the specifications. is there anything specific to worry about? am i going to mess up my timing if i put the distributor in wrong? do i need to get the heads decked? is there any other special conditions i should know about? thanks!How do i change a head gasket on an '85 monte carlo ss with a 305?
the heads shouldnt need to be decked, unless of course they are warped. as for the timing, mark the number one plug wire on the cap before taking apart, and make sure to bring the number one cylinder to top dead center before taking apart as well. get a chilton book, you can get at any parts store. tons of info in them. the 305 is one of the easiest to do heads on, or any chevy small block for that matter.
