This is the Sierra 18-3899 gasket, listed as a gaskethead for E/J applications and also carrying the number 327674. Nothing further is stated about size, material or engine fit, so confirm the numbers against the old gasket or your engine's parts diagram before fitting it. Sierra's number and the 327674 reference are the two identifiers to match.
Our take
The only identifiers stated for this Sierra gaskethead are 18-3899 and 327674, plus the E/J label. With nothing else listed, matching those numbers to your existing gasket or parts diagram is the way to confirm it fits.
