What Is Fire Ringing?

With fire ringing, the stock steel fire ring in the Cummins gasket is removed and instead replaced with the mild steel "fire rings". This allows for a stronger seal than o-ringing. When the head is torqued, the steel rings will crush, allowing a strong seal.
This application will hold upwards of 100PSI of boost when using the correct fasteners. When you machine both the head and block, about half the recommended machining depth is used on the head and block, this way, the rings are set in both the head and the block with even less chance of them shifting when re-installing the head.

Yup you read right 100PSI OF BOOST!

All of our engines are rebuilt with new rings and pistons, freeze plugs, lifters, timing components, crankshaft, oil pump, and gaskets. We regrind, polish, and chamfer oil holes to rigid specifications on all crankshaft's. Rods are checked for any bends or twists, resized and honed to O.E.M. specifications. Valve seats are 3- angle cut for the perfect seal. Heads are cleaned, magnafluxed and pressure checked, and completely rebuilt. Blocks are cleaned and magnafluxed to ensure unseen cracks do not cause premature failure. Then, to assure proper sealing, block decks and cylinder heads are resurfaced. Finally, we regrind and thoroughly inspect valves on stock engines, and we only use new valves on all performance engines.
