Some Information about us.
  • We are a Manufacture of Billet Valve Cover Spacers and Adaptors.
  • All of our Spacers and Adaptors are Made in USA with USA Made Materials. 
  • With Medice Manufacturing Valve Cover Spacers you no longer have to use tall valve covers to clear enhanced-performance valve train components.
  • Utilize your factory valve cover (or any valve cover) and gain space for high performance valve train parts/components.
  • We also manufacture valve cover adaptors / conversion kits to put different valve covers on different engines.

Some information about installing our valve cover spacers. 
  • Use a good quality silicone to seal the spacer to the head.
  • IF you are using a tin valve cover (once again MUST be flat) I recommend a gasket between spacer & valve cover.
  • MOST IMPORANT everything MUST be clean & MUST use a good quality gasket.
  • The BEST silicone I have found is Ford Motorcraft RTV for use on 7.3 Power Stroke Diesel Engines! Motorcraft Part number (TA31). You can get it at your local Ford Dealer.
  • We also enclose an information sheet with each set of spacers sold.
