Store them wet or dry?

[f_inscreenname]

Just got my new set of GLM aluminum exhaust manifolds. As you can see in the picture they come with zincs and drain valves. I know that zincs will not work unless they are in water. Just not sure what I should do. Flush and drain, flush and leave full??.What do you think?

I don't believe it.
Obviously GLM doesn't understand that zincs like that corrode and fall off in chunks. Then, in the small narrow passages of an exhaust manifold and/or riser plug up the smallest hole.
Personally, I would pull the zink out and put the plug in.

Yep...I'm with Don 100% here...plug'em. I have a pencil Zinc in my ALUM Intake Man (350 GM, but that water is always there and in the block any broken chunk would get wasted in a passage way..(?), and Saltaway after use.. I replace yearly at still 3/4s left..6 weeks in). But the Exhaust man's..hmmm...I'd just flush ..Saltaway if called for..
Thats some small openings pushing water into that riser into the exhaust...plug too easy the way it is..
