Match the gasket to your Stahl-pattern header build
The Kooks PY-8017-AL supplies a pair of multi-layer aluminium header gaskets for the 23-degree small-block Chevy Stahl-port application. The seven-bolt Stahl pattern is the key detail when choosing this specification for a custom or replacement header installation.
SKU: PY-8017-AL
Choose for the actual port and bolt pattern
Match the Stahl port and seven-bolt arrangement to the cylinder head and header flange. A general small-block Chevy description alone does not establish that pattern.
