We have been getting alot of calls lately for our valve spring and retainer kit for the Ford GT/GT 500 heads. It seems alot of people were not aware we had this kit so we figured we would post some info for those looking to upgrade springs or add cams.

The kit allows use of any 4v camshafts up to .550 lift -open and closed pressures available upon request

The Kit includes Gt 500/Ford GT specific intake and exhaust beehive springs manufactured for us by Manley along with custom MMR/Manley Titanium spring retainers. These kits require no machine work or modification and work with the factory valves. This is the same kit MMR has track and dyno proven beyond 3000HP in our Pro Mod 5.8 DOHC Twin Turbo GT500 and the worlds fastest GT500!!

These kits are also great for High boost applications to prevent the intake valve from opening from excessive pressure on the back side.

Kit Price is $899

Out of curiosity what kind of power gains do you typically see between stock GT500 heads and ones after you do a full port/cam/etc job to them all other things being equal?
