FYI-
VW Motorsport endorses and uses Raceware Fastners in their machines!
Quite a few Dealerships carry the Raceware head bolts!
The Raceware's are without a doubt, the way to go, when building a more
powerful engine!
Audi Sport recommends utilizing a "stud" kit and "special head gasket" in
applications
over 16psi boost! Especially for the 20V, which Audi makes a special "kit"
for the application!
