Hey all,
The motor is going back together, and upon close inspection of the heads, there are some small pinholes along the sealing surface of the head. I'd like to drop the head gasket and lap the cylinder to the head, but will these holes be a problem? Based on the measurements, the pinholes will be 0.016" outside of the ID of the jug, and as such, covered by the jug. But is that enough? Can I run this as-is? Lap the jugs to the heads, and run sans gasket? Should I run I gasket? Or should I have the holes welded up and re-flycut the heads? There's all of about 40 minutes run time on these heads right now. Thoughts? Experience? Thanks! -Josh2 |

Are the literally holes all the way through or just casting errors like maybe a bubble was cast into the metal? If it's just a bubble, then I'd guess it's not a problem. Seems to me the thickness of the cylinder mating surface would cover the holes. I wonder if filling in the holes with JB weld would help. Cap'n? Jake?
