Had the intake port TIG'd to repair a chipped shoulder on the bottom of the valve seat bore in the block itself, as a result of the valve seat coming loose. Need to bore out the excess material and to accommodate the oversized seat I'm going to install. However, without spending some very tedious time, indicating off a pin in the valve guide, and sweeping the block on the cylinder end, I'm wondering if anyone has the spec on the angle at which the valve seat bore is from the cylinder end of the block. I could also square up on the end of the head end of the block, and sweep the face of the adjacent exhaust valve to determine the angle (closely), but would feel more comfortable if I had the spec on the angle, as the block was originally machined, simplifying the set up on the Bridgeport, and me being able to sleep better knowing I used the factory spec, insuring my angle alignment to the valve guide bore.
