I have the bare undamaged Cylinder heads off my own 2007 Ron Fellows Z06 for sale. They have 22,000 miles and were removed when I found titanium in my motor oil. They were not damaged but require valve guide replacement and all the head components as they are bare heads. They are Z06 LS7 castings great for a performance build. I sold my Ron Fellows and now drive a 2014 LT1 so I need to let them go to a LS7 guy that needs them. Asking $500 plus shipping, I am located in Northern Virginia. Offers will be considered. Dennis
