Problems with early M&A aluminum heads?

[Turbo1dr]

Just to refresh my memory...what are/were the common problems with the early M&A aluminum 14 bolt heads? The GN I just bought has a set and I'm planning to swap them to my Malibu. These heads probably have 10,000 miles on them.

Some leaked water and some with high spring pressure would crack the rocker hold down area.
See ya, Kip

Does anyone have pictures of these cracks? I'd like to add more metal now instead of after I get them on.

I have a set that is being installed, I am not sweating very much since they were off a running car. I would be hesitant if they were already off the car. I don't think you got much to worry about, nor I.

What exactly is a rocker hold down area?
