HEADS:
Very very nice set of c5r race heads from katech . these were development heads for the compuserve corvettes . these were developed for there 427 inch motors to make alot of torque to come off the corners for a killer road race head . these take a 2.150 intake and 1.62 ext both 11/32 stems . heads have berillium copper seats and bronze guides . the intake ports have epoxy(not repair) in them to mold the port the way they wanted its a very trick intake port . these will work on any ls1 ls7 ls3 block . castings cost $3,000 from gm and these are alot beefier than a stock ls1 ls7 or l92 head there made to take the abuse of racing . will work with 4.120" minimum bore.
