I had trouble fitting this manifold while doing a head gasket job. I ended up having to grind the bottom to clear the coolant pipe running underneath from the water pump to the oil cooler. I also had to enlarge one bolt hole, second the last bolt on the top from the rear. It was several sizes smaller than all the other holes and did not allow the bolt to be threaded in.

Bolts that come with it are way too long. Wish it came with heat shield. Tried to use old heat shield but bolt holes don't line up to re use the old shield.
