I just installed dart pro1 heads on my ls1. The dart chambers are quite wide so it was recommended to use the ls2 head gasket. I suspect you should do the same thing as the ls1 head gasket will probably shroud the ls2 combustion chamber.
I'm confused on the situation, lol, because some of my customers have purchased the LS2 gaskets for this and some have purchased the MLS... so who knows!

Either should work fine when used on a LS1 engine..
The LS2 gaskets will have a larger bore dia,, since the LS2 engine has a 4" bore vs the 3.9" LS1 bore. .
You can use a larger bore gasket on the smaller bore engine, but not the other way around. (LS1 gaskets will not work on a LS2).
