Grade 8 Best Quality Header Bolt Kit for B/RB-Engine 12 point 3/8" Head HBB12
This kit fits all B/RB V-8 Engines. This kit is comprised of the Finest Quality Grade 8 Header Bolts for B/RB-Engines. They are 3/8"-16 X 1" with a 12 point 3/8" Head for those tight places to get your headers tightened correctly. Using a 12 point forces you use a 12 point wrench or socket to get the desired torque, not allowing you to use an open end wrench that only allows less than 10 lb. ft. of torque on the bolt head. These Bolts are longer than the competitions bolt, to allow for the 3/8" Thick Flanges found on most all quality headers now. Will work on 5/16" Thick flange headers found on older or less expensive headers.
Bolts are Black Oxide Coated for long lasting performance
Kit includes 12 Bolts, enough to do most Big Block Mopars
NOTE#1-Sealer should be applied to all bolt threads on Big Block Production Cylinder Heads to stop any coolant leak when your headers are reinstalled. RTV is a good sealer. Just apply to thread grooves.
2-Proper Header installation should achieve 25-30 lb.ft. of torque. Headers should be retorqued after one heat up and cool down period. Retorqued in one weeks worth of driving and rechecked in a month of driving. If these steps are performed you should never have a header gasket failure
