Intake/exhaust manifold install … failed attempt #1 … need advice (1 Viewer)

[Steamer]

Followed Remflex's torquing recommendation. Tightened the manifold bolts down to approx. 23 lbs, and the riser to about 20 lbs.

I don’t recall the duration but I believe it’s advisable to re-torque the manifold bolts after a certain amount of miles/hours or hot & cold cycles. That's with the oem gasket anyway. The Remflex may be different. Maybe someone here will advise.
