I visited my engine last week. Here are a couple pictures of the cylinders in question (those where the surrounding head-bolt threads were pulled out of the block). I think I still have the spiral of aluminum threads in my jacket pocket, showing how the aluminum threads sheared of as the bolt pulled out.Anyway, any thoughts on the the condition of the cylinders? The scratches are pretty minor but I could feel them with a thumbnail. I haven't heard what the engine shop thinks yet. I will be replacing at least the valve guides, main and rod bearings, and rings. I'd like to avoid sleeving the cylinders and replacing pistons, but that may change if the pistons show any issues. I will likely be moving to a high-boost pulley, as I am adding an F/IC and 550 cc injectors.Thoughts?
