Dress Up Your 401-425 Buick Nailhead Engine with our stainless steel hex bolt kit!! This kit has a natural stainless finish.

Our kits are also available Polished with the stamps and marks still on the heads, but they are shined to a very high shine. We also offer our Show Polishing. We remove all stamps and marks and polish the heads to a mirror finish. The bolts have the appearance of Chrome without the headaches.   Let us know if you want either of these services at the time of ordering and we can do this and price this for you.
We Use Only The Finest 304 or 316 Stainless Steel Fasteners In Our Bolt Kits. All Bolts have Rolled Threads! We use our extra thick intake washers and longer bolts in this kit. These washers are 1/8 thick and have a smaller center hole to keep the washer centered on the bolt.  Our washers are specially made for us in the USA to our specs. Other sellers use thin small OD washers which will bend down into the mounting holes in your intake and shorter bolts in their kits.

If you are using aftermarket parts on your engine, let us know and we will custom build a kit that fits your combination!  Please include a note with your payment listing any modifications.

This is a complete high quality stainless steel hex bolt kit. The kit includes individually packaged and labeled component kits for the following:

Intake Manifold Valley Cover
Timing Cover Water Pump
Oil Pan Oil Filter Housing
Thermostat Housing
Distributor Coil Bracket
Fuel Pump
Valve Covers Headers, Crank Pulley & Fan Pulley Carb Stud Kit

We don't use AN washers on all of the bolts in the kit like the other kits out there! Other sellers use these thin small OD washers because they can include washers on all of the bolts in a kit for less than $1.

Alloy Boltz uses larger OD and thicker flat washers through out our kits.  Many of them are custom made in the USA to our specifications. All of our washers are run through a polishing process to make sure they look great!

Our washers give more support to your oil pan and valve cover rails making them less likely to bend under the bolts which will cause the gasket to pinch and lead to oil leaks. We also add split lock washers on some of the kits to make sure things stay tight.
AlloyBoltz Pays Attention To The Details!


The carb stud kit fits Carter, Edelbrock, or Holley Carbs. The studs have an internal hex used to install them in your intake manifold. If you are using a Quadrajet carb, just let us know and we will include a mounting bolt kit for you!
