Question
Hi Tom, I am about ready to install the new head gaskets on my 1990 Buick Century Custom with a 3.3.  Can you tell me which bolt to start on and the sequence that follows it?  Also, can you tell me the torque pounds to use on each sequence? If you can send a diagram or picture or website that give this information, I will be sincerely grateful. I want to do it right the first time. Again, I thank you for your time and information.  Stephen
