98/806 heads on 6.0 for FI?

Can these be used on 6.0?
If so am I stuck with the 98 graphite head gaskets or could I use a mls gasket?

Yes And No

Yes you can use the perimeter bolt style heads on a 6 liter. and yes you can use Metal multi layer gaskets.(recomended)

So I can use these on the 4.0 bore with mls gaskets

Is the small bore head going to hurt me in the power department?
FYI these are the heads used in my sig nicely ported
