The real problem is losing the deck strength and integrity. Unless it's hard blocked to the top things will move and no amount of sealer or loctite will be a lasting cure. In essence, the only support for the deck becomes the head bolts, and they're located far outward of center which leaves a big area unsupported. This is why Bob Glidden used to furnace braze the liners into his blocks during his Cleveland Pro Stock days, but that requires a complete remachining of nearly every surface. I'm actually impressed Mario's engine lasted as long as it did. The Poor Mans 427 had issues from the first run. Regardless if Wes thinks they found the cure, it has not been ran for any length of time in a real world environment, and I would not count on it surviving long without issues.
