It's hard to tell. I'm pretty sure the rear cams were dead on. I know my front exh cam was off by 180, I think I either went too far or not far enough to get to the #2 timing mark when installing the cam chains. I had a ton of trouble installing the tensioner in the front head, everytime I put it in, it would ratchet up and take the timing off. I went through it again and again and finally got it to line up correctly. But the rear head went smoothly, on the mark the first time. I had bought the "low mile" heads off e-bay last fall and dis-assembled them for new seals and a hand-lap job to check the seat width, and all looked good, plenty of assembly lube. I don't know, I'm pretty dejected about the whole thing now. Spent every dime I could spare to build it and now it looks like I've got parts to sell. We'll see if an engine becomes available that I can afford. I've still got my original 85 heads that were working so that destroyed head is not that much of a concern, however the crank is probably toast as is the upper crankcase, oil pump and who knows what else. On the plus side, I can tear it down in about 4.5 hours now.
That's the new plan. Gonna have to wait till fire season is in full roar, hopefully get some good overtime to be able to afford anything. Life has a way of bringing you ups and downs, hoping the ups come soon.
