Patrick, I have no ID on my manifold. It just says DOVE on the breather adapter for the PCV valve. I am sure that was purchased separately or after the car was built.
I just went thru all the paperwork I got with the car including the engine build parts list. On that list it says "1 BT 1x4 Int". Could that BT mean Blue Thunder? Does your manifold say "blue thunder" on it?
So, 32 ft lbs? Do you have steel heads? I'm thinking that spec is for steel heads.
I have the Edelbrock aluminum "performer" heads and it calls out 25 ft lbs for the manifold bolts. I would think that would be pretty important since the threads are in the heads.
