Factory Exhaust Manifolds
« on: January 27, 2018, 03:47:00 PM »
I’m trying to replace my factory exhaust manifolds and found some used ones off of an ‘85 K-5 (that’s all the info available). I’m assuming if it’s a small block, they should bolt right up to my ‘87 Suburban V20, correct?

Also, any advice on getting the manifold bolts out without breaking them? They’re looking intensely rusted.

Thank you, guys.

They are different manifolds. I would recommend getting new manifolds. They come with studs, gaskets etc.
