That is a good question and a big part of my frustration as I never got a straight answer to that question. We did not machine any surfaces of the manifold, so my guess is that the heads had been previously machined and the original manifold machined to match. My guy just put the manifold on and it appeared to seat, so he assumed it was set right. If it is off, it can’t be by much. I know that I should probably pull it apart and measure, just thinking that the fuel injection might be an easier way to go at this point.
