Default Head Studs for Edelbrock Pro Ports

Does anyone know what head studs are used with the Edelbrock 11 degree pro port heads?

I've heard those heads can be made to flow some really good numbers,
And them being an 11 degree heads will make some serios HP

They'll flow 460-480 depending on port work.
