I had a similar occurance with Erics work. Great overall, but the piston was knicking the powervalve at idle. Eric sticks to some pretty close tollerances to get the performance he does I think. I returned it to him, he repaired it and shipped it to me overnight Saturday delivery and paid me for my shipping to him with a check in the box. Awesome, intelligent, hard working, great guy. I wouldnt go anywhere else.
I would, however, try to loose some of this 210# old body to gain a better HP to weight ratio! Even with the extra weight, the 144 hauls the mail.
