This gasket combined with the 5.7 liter kit (Standard Motor Products 1703 TBI kit) saved me about $75 on a rebuild of my 1992 Chevy C2500 7.4 liter throttle body . You'll still need a fuel pressure regulator spring (few people ship to California and mine weighed a few extra pounds so I won't post it here and don't confuse anyone) and inlet/outlet o-rings (Dorman 800-013 Viton o-rings) . ).
