While those are all valid points, its not how I am going to do it. The pistons, I dont want to see them, they live a hard life. Ill do new valve seals when the head studs go in, I ordered Comp 910s with the studs. Eventually I will buy a core engine and rebuild it correctly, but for now Im just tinkering. If it grenades because of my lack of prep work, so be it. Not the end of the world. The goal is to throw it on the dyno in September, see what I can put down without going into the engine.
