tom s,
I did send the link to this valve cover from Butlers before I purchased them. Paul said it was good, he just had to use a thicker gasket. He suggested the gasket and I sent him the gasket and valve covers. He checked it for clearance. When the knocking was discovered, thats one of the first things that we checked. I have pictures of the inner valve covers in my phone.... somewhere. There were no witness marks. I doubt very seriously that Paul would have missed that. What is it that you see on the dyno picture?

DOC,
Great suggestion but I would hope that Paul would have done that when the motor was reassembled after he tore it apart.

Formulajones,
Yeah ok. Since you're an uninvolved, biased participant in this, I understand what you're saying. No need for me to comment any further.
