First of all I want to Thank all the members here who have offered their advice and parts when needed. You all have been a big help with this project which is my first start to finish build. There are posts on the A body site under "here we go again" that show all the pics and issues in the /6 header. I finally got it running and did the cam break in without mufflers on the headers. Boy did that shut up the neighbars chiuauas for a while....Ahhhh peace. Now I went to start it and there sounds like air coming out of the exhaust so I shut it down. Sound like lifter adjustment time? I haven't pulled the cover off yet due to other things needing to be done so I am open to suggestions. Thanks again for all the help I look forward to the time I can return favors to others.
