I need to find the brass sleeve that sits in the head bolt hole on the engine block. Does anybody know if I can just buy one new or if I have to find one off another block and replace it. Also, I have the flowtech long tube headers, I know they're crap but I'm using them for now. My question is will any h-pipe fit the headers or do I need a custom one or the one from flowtech. I heard usually you need the same brand h-pipe to match the headers, otherwise they may not fit together properly. Any info. would be great.
