426 Hemi Cross Ram Faseners?

Well, what ever it takes as long as you got it secured to the heads... no, always interesting to hear how you do things...
I was thinking of only two being studs in two of the corners, but not sure what´s best here.
Don´t think there is a special set of screws and studs for this Cross Ram? May be the ´66 Street Hemi Intake bolts and studs is working fine?
How do you do it? What line up do you use here?
Pic is 1973 state off the art Diamond prepared piece.
Grateful for your advise…
