Flowtech 99150FLT Real-Seal Header Gasket Round Port for Select GM

FLOWTECH REAL-SEAL header and collector gaskets are a revolutionary break-through in exhaust sealing technology. Constructed of separate layers\nof "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\ngasket 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\nyou can use them over and over again.
