I was going to comment that if you were going to re-use the same intake on the new engine, be sure you clean out the manifold. I have seen bits & pieces of rings & pistons get sucked up into the manifold & cross cantaminate parts into other cylinders. That said, the price is pretty good for a complete running 400 motor. Make sure everything is clean before assembly. Make sure no old gasket material/dirt/debri gets in the mew motor. Go slow & double check everything & it will be fine.
