I have for sale a set of vintage Moroso chrome valve covers off 1970 383 w/ 906 heads. Have been told they also fit 413 & 440 engines. These are from the mid-to-late 1970's. This older style is no longer manufactured. They do have light scratches as expected for their age. There is a very small area of surface rust on the top of one cover (see photo). $95 + shipping/insurance from zip 50036. Payment via PayPal and we will provide you with a tracking number.
