FS: Ported LS1 heads w/ Brand New Patriot Gold Dual Valve Springs These heads are the 853 casting LS1 heads ported by a well known local speed shop (Bay Speed). I paid over $550 just for the porting alone. The valves have also recieved a CNC valve job. The heads were not shaved and have stock size valves so they will fit the bigger cams like the TRex MS4 etc... They were flow benched and made significant gains over the stock heads. I appologize that I dont have the exact numbers, but I do have all of the sales receipts for all the work and testing done on the heads. The heads are fitted with a set of Brand New Patriot Gold dual springs, New Valve seals, and spring seats. I am asking $550 plus shipping. Some pics of the heads are bellow.
