Could someone please answer a few questions about the correct style/placement of the intake manifold bolts/studs on a 1972 455HO.

1. What style bolt would be used in the positions that only use a bolt.

2. Approximately how far from the cylinder head should the studs extend that attach the intake/crossover? These are 3/8-16 thread where the washer/nut would go on them aren't they?

3. Not sure my diagram of the placement of the fasteners is correct.

Thanks is advance-Kyle.
