Bosch Man,
Now on WRC middle 6 long stud std out 4..as my block came with this...have full confidence on this as the middle 6 is where the most force is and my head wont lift like it would on std head bolts and crack around bolt holes!IMO its all thats needed as the outer 4 do not want to be as tensioned as the middle 6 (std are stretch,WRC are semi stretch) or block cracking can occur again culminating in premature gasket failure
