Im not into the bling factor but ARP makes SS 10mm X1.25 x55mm or 48mm long studs that would look great

Why pay $68.00 to install stainless steel studs that are about 3/4 the strength of the stock studs and increase the potential for having head gasket problems?
Why not just install acorn nuts on the stock studs and you will not be able to see the studs?
