I have used them in the past with no issues. Coat them with something before using. They make sealers for steel shim gaskets.

like that copper brush on stuff?
I used GM gasket sealer. The brown liquid stuff with the brush in the can. You can use a variety of sealers, lots of different ones will work. I believe there are some good spray on sealers now. Some people have used aluminum spray paint. You might ask the question in another post, I'm sure you will get some answers.

I used to use them all the time on my 427 with iron heads. I actually installed them dry....never used anything on them for over 20 years of working on that motor. Even ran a 2 stage N20 system with them..no problems. No water leaks etc. Block was never decked ot trued..but heads were when they were milled.

Install them with *beads* down.

I ordered a set of them last year for my 496 and they did not fit the block or heads correctly. Maybe just one bad set but I had gasket laying over into the cylinders and they wouldn't even fit the dowels correctly. I ended up going with the GM shim gaskets #14015351. I ordered a few sets of them as they are now discontinued.

Best sealer I have found for steel shim gaskets is just plain ol' high temp silver paint they sell for barbeque grills. Brush the stuff on good and thick, let it air dry for just a couple of minutes, then install and torque the heads while the paint is still tacky. BTW, you will get paint all over your fingers, hands, etc.

Now that you mention it...let me update my post.....I DID always have to use a die grinder in the dowel holes to slightly open them up on one side to get them to slip down over them.

Forgot that part....but it takes 10 seconds and they are cheap and work well!

Yes, and I had to trim a little for the valve reliefs in the tops of my cylinders as well. Nothing a die grinder wont take care of.
