Have any of you guys with trouble getting a head gasket to seal put a straight edge on the top of the block? How about running a thread cleaner in the head bolt threads in the block?
Just a couple thoughts. Thanks Don Super 300 is vegetable based and the aviation NO. 3 what I've used is a modified resin. http://www.permatex.com/documents/tds/Automotive/80018.pdfhttp://www.permatex.com/documents/tds/Automotive/80057.pdf | | |
