L30/L31 Vortec engines use fasteners made specifically for the plastic Vortec intake and intake gasket. To prevent over torquing the fasteners and crushing the intake gaskets, the bolts come with a longer shank having a non threaded bottom portion so as to bottom out before the gasket or intake sealing flange/bolt hole is compromised.
