Flowtech 99150FLT Exhaust Header Gasket

Compatible with 262-400 Chevrolet Small Block Gen I 1955-1991;

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 will not 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.;
