Does anyone know if there is a difference in the 850(non-turbo) exhaust manifold between a 10 valve fenix 5.2 and the more common 20 valve engines. I have a 10 valve volvo and found a good deal on a manifold, but I've learned the hard way not all 850's are the same. Any info would be greatly appreciated! Thanks.

 

I am almost positive that the manifolds are different. I would keep looking for one for a 10 valve engine.

 

Thanks, I figured as much, do you happen to know it there is an engine code on the manifold somewhere? or if there is some way to distinguish the two types looking at just the manifold?
