head gasket repair

Hello skyler--  The best site I know of for repair and maintenance information is www.autozone.com.  It is the consumer version of the Alldata guides that are sold to repair shops everywhere.  For your 1995 Chevrolet Blazer start at the following site and go from there.  It isn't a college education, but it will give you a good indication of what you are up against.  http://autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/18/b2/68/0900823d8018b268.jsp.   Good luck from Bovan.
