Flowtech - 99153FLT
Header Gaskets - Aluminum-Layered - 396-454 Chevrolet Big Block Mark IV 1965-90
Header Gasket Set; 1 Pair Header Flange Gaskets; Rear Seal; Round Port; Dead Soft Layered Aluminum;
FLOWTECH REAL-SEAL header and collector gaskets are a revolutionary break-through in exhaust sealing technology. Constructed of separate layers of "Dead Soft" aluminum, REAL SEALS provide a do-it-once solution that will not burn or blow out. REAL-SEAL gaskets will work when an o-ringed gasket won't because the "Dead Soft" aluminum conforms to create a leak-proof seal. REAL-SEALS can also be easily trimmed for port-matching and you can use them over and over again.

- Will Not Burn Or Blow Out
