pipes

[buster024]

So any tips on getting header pipes back together again once they've been pulled apart? I did some polishing on my Yosh headers and pipe system, and I'm struggling getting the pieces back together again. It took an act of God to get them apart, and it's even worse getting them lined up and shove back in.
I tried a little WD40 on them, but very little luck. I don't want to grab them with channelocks and scratch them all up.
