Re: Vortec intake Gasket fitment
No extra sealant at all, and I always use the GM bolts.
They are rounded on the bottom, but they don't really bottom out when torqued to spec. This can be checked by using machinist's dye or paint on the bottoms.
Torque and sequence are critical and I go over them several times.
I've also seen regular 5/16 bolts used with no problems.
I copied this from Wiki:
The Torque order is the center bolts in an "X" pattern followed by the outers in a line pattern. Following the cylinder numbers of 1 - 8 (1, 3, 5, 7 on drivers side, and 2, 4, 6, 8 on passenger) you would tighten them down 3, 6, 4, 5 for the "X" pattern, then 7, 8, 2, and finish on 1.
You tighten them down in steps
1st round goes to 26 in lbs.
2nd round to 106 or 116 in lbs.
Then last round is 11 ft lbs
