2-Piece Valve Cover Kit for Big Block Chevrolet
These valve covers are not only the most beautiful addition to any Big Block Chevrolet marine engine they also solve one of the most difficult and annoying tasks for power boaters, inspection and adjustment of your engines valve train!
The PATENTED two piece design allows access for inspection and maintenance without removal of the exhaust system. Once the receiver rail is installed you will never have to worry about cleaning, replacing, or scraping valve cover gaskets again. The patented valve cover receiver rail stands 3/4" tall and prevents oil from running down the side of your engine while the cover is removed. A positive o-ring seal assures a leak free seal between the covers and receiver rail, but best of all the cover is removed via two integrated thumb screws. That’s right no tools required here. The cover can be removed and replace in just minutes. Allowing more time for what you want to do most — powerboating.
NOTE 1: You should tighten the valve cover rail to head at 130/120 in lbs. and the wing nuts to 25/20 ft lbs.
NOTE 2: Purple, Red, Yellow, Silver and Black Colors will have two week lead time.
