Hex Head Black Oxide Intake Manifold Bolts for Ford 351W, uses 3/8 wrenching

Hex Head Black Oxide Intake Manifold Bolts for Ford 351W, uses 3/8 wrenchingPrevent intake manifold leaks with ARPs quality fasteners. Theyre nominally rated at 180,000 psi and precision machined for optimum thread engagement. Wide underhead flange and companion washers provide even load distribution. Precision rolled threads prevent galling while promoting more consistent torque loading. Facilitates optimum sealing of gasket surfaces. Available in choice of black oxide finish chrome moly or corrosion resistant stainless

ARP has designed an extra heavy-duty shaft that will provide you with the necessary reliability

which requires less energy to operate

rated at 190

Most applicationshave undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for theadditional compression of gaskets

with threads rolled after heat treat to ensure the optimum fatigue strength

Stock fuel pump pushrods leave a lot to be desired

Made from ARP2000 and heat-treated to 220

Because ARP studs are manufactured to suchexacting tolerances

there’s not a better stud setupon the market today

If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in – you knew from the beginning that the rocker geometry was going to be inconsistent all over the place

This procedure (done only to the shorter studs)more equalizes the “stretch” of both studs

They’re made from premium grade aerospace chrome moly and centerless ground to precise diameter
