454 intake manifold bolts

Do you have a set of 1970 454 intake bolts to sell? The ones I have seen in photos are the shoulder type with recessed heads with headmarks of M inside a circle, NAT, FP, or TRW with three hashes. They are black oxide in color.

Thanks,

I do not have any sets of bolts other than a set of ARP bolts for the intake and head bolts.
