Many thanks for posting this info. Might have an opportunity to put this to use on a set of magnum heads.

I've recentely (3 months) had a piece of steel drilled out of my eye. It sucks. I took care to use my glasses and some sealed goggles, but I actually got the chip in my hair and it washed out into my eye later that night . Maybe a hair net is in order

Hope this gets to the tech archives. It would be great if you could make a general post about where to look for air, and augment it with where you found good results on the various mopar heads you've worked on so far. You're becoming a real faucet of knowledge. The board is a much better place because of great guys like yourself!!!
