Does any one know what the NTPA spec for exhaust cross bolts is?

Most all rules state 3/8inch bolts 1inch apart in a criss/cross pattern within 12inches of the turbo

The NTPA rules book reads as follows: Turbocharged engines must have (2) 3/8-inch bolts (Grade #5) in horizontal position of exhaust pipe(s) as close to the turbo as possible. Bolts to be installed 90 degrees to each other, within one inch of each other.
