By the way, I needed to send a public update and apology to those waiting for parts and heads. I had been putting off knee surgery hoping my machinist would get the work done I had taken to him over 3 months ago. Well, on August 28, I couldn't wait any longer. The knee got scoped out. I spare you those details. Following that I caught some flu bug that just kicked my butt. I plan on getting back at it this weekend. So thatnks for your patience and understanding. I'll be absorbing all the shipping costs as a result. It is the least I can do.
On a different front, I have an opportunity to do some work for a company that is R&D on the 5.7 heads. These heads are pretty decent out of the box and I have a 23 cfm improvement on them with the stock valve job and valves. The cfm improvement is almost equal on intake and exhaust. I hope this pans out!
