I've known Joe for a long time, probably 20 years. I visit him just about every time I go to Albuquerque and used to hang out with him quite a bit when I lived there. He is a great guy, very knowledgeable and willing to share that knowledge. He's flow tested dozens and dozens of heads stock and modified and has a book with all his data in it that I've perused...very enlightening.
I like his approach - he validates things on the flow bench, proves them on the dyno, then drives it and revalidates it on the drag strip. He's got some neat cars!
Proud to call him a friend.
