If you add any lubricant (say a Never-seize type compound) then the torque specs are lower by at least 10%. I also searched around for torque specs on bolt sizes. Again depending on the grade of the bolt, torque specs will vary. Here’s a link: Botl Torque by Grade I believe the bolts are 10mm x 1.25mm thread count.

How big is an exhaust manifold pipe nut?

The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft.

What are the torque specs for a corvette?

GM introduced the second-gen LT1 in the 1992 Corvette as a modern update to the original small block. Most of the LT1’s parts interchange with its predecessor’s, and bolt torque specs are similar. Torque the LT1’s exhaust manifold nuts and bolts to 30 lb.-ft.

The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft.

How big are the bolts on a botl manifold?

Here’s a link: Botl Torque by Grade I believe the bolts are 10mm x 1.25mm thread count. Might be 1.5mm thread count. As for the sequencing. Start in the middle of the manifold and work outward, alternating side to side. Also move in steps to your final torque setting.
