Yes, aluminum heads.
To be honest, i've used steel shims with aluminum heads (even though they say not to) and never had a problem.
But steel shims are out of the question now anyway, since they will put me under .030. In the past I've always used them to get my compression up on stock blocks.
I have a pair of the MOPAR shim gaskets and they are actually 0.017...I wonder how much the copper spray adds to the thickness? wink
