Default Valve Cover Gaskets

Does anyone have any recommendations on the best type and brand of valve cover gaskets (eg. cork, rubber, velcro, etc.)?

Thanks

Fel-Pro or OEM AC Delco only.

They are silicone rubber and fit into a groove in the lower flange. Easy to do. Torque specs are in Techinfo.

It means..tighten to the torque spec..then turn the handle of the wrench another 90 degrees after the spec was met.

Another way to explain it..if you meet the torque spec and the wrench is pointing to 3 o'clock..you turn it until it reads 6 o'clock which is 90 degrees.

I have a feeling those torque to yield instructions are for “rocker arm bolts”.

Can someone please double-check this?

My 96 manual says.

Rocker arm covers and / or gaskets.

1. Rocker arm cover bolts and cover.
.Apply thread lock compound or equivalent to bolt threads.

Tighten
Bolts to 10 N.m (89in. lb.)

Yessir! If you do valve covers at 10 ft lbs + 90 degrees, I think it'll break a valve cover.

My '97 FSM and Chilton'* both say 89 INCH pounds.
