KMJ Performance sells a similar valve cover I am using on my 327, and they're really nice quality for a very cheap price. And yes, they are a baffled inlet too! I like them because the mounting holes are sleeved so they use a long allen head screw, and not cut out around the mounting screw. $59, with free shipping too!
