98 heads with the notch usually leak coolant with the MLS gaskets unless something has changed. I haven't tried to use them in quite a while.

If you are going back with '98 heads you have to run the graphite gaskets. If you are putting a newer head on it, you will be fine with MLS gaskets.

I read if you use the Mls they will leak coolant.The head castings are 803's.Thing is that My brothers 98 z28 had some Mls Head gaskets installed from previous owner,dont remember any coolant leaks.
