Lol.
Yes,I'm sure. Can't remember exactly which ones,but there are a couple studs that go into the water jacket. These studs need to be installed with a sealant,before they go in.Yours are locked in,and didn't turn when you removed the manifold.
Sorry Mike...So how bout that Distributor. :burnout:
Oh duh! Yesterday I was thinking that the manifolds bolted to the head instead of using nuts and studs lol! I told you how chitty my memory is. Well that would explain why I don't remember doing anything with water.
