Engine Cylinder Head Bolt Set, Victor Reinz 14-10049-01

Engine cylinder head bolt set using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with tty (torque-to yield) head bolts, replacement is an absolute necessity. tty bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used.aplication summary:chevrolet - 1985-05 astro v6 4.3l, 1995-05 blazer v6 4.3l, 1985-86 c10 v6 4.3l, 1988-98 c1500 v6 4.3l, 1985-86 c20 v6 4.3l, 1988-95 c2500 v6 4.3l, 1985-90 caprice v6 4.3l, 1992-93 caprice v6 4.3l, 1992 commercial chassis v6 4.3l, 1985-87 el camino v6 4.3l, 1996-13 express 1500 v6 4.3l, 1996-05 express 2500 v6 4.3l, 1985-95 g10 v6 4.3l, 1985-95 g20 v6 4.3l, 1985-96 g30 v6 4.3l, 1985 impala v6 4.3l, 1985-86 k10 v6 4.3l, 1988-98 k1500 v6 4.3l, 1985 k20 v6 4.3l, 1988-95 k2500 v6 4.3l, 1985-88 monte carlo v6 4.3l, 1990-99 p30 v6 4.3l, 1987 r10 v6 4.3l, 1987 r20 v6 4.3l, 1988-04 s10 v6 4.3l, 1988-94 s10 blazer v6 4.3l, 1999-13 silverado 1500 v6 4.3l, 2007 silverado 1500 classic v6 4.3l, 1987 v10 v6 4.3l, gmc - 1985-86 c1500 v6 4.3l, 1988-98 c1500 v6 4.3l, 1985-86 c2500 v6 4.3l, 1988-95 c2500 v6 4.3l, 1985-87 caballero v6 4.3l, 1985-95 g1500 v6 4.3l, 1985-95 g2500 v6 4.3l, 1985-95 g3500 v6 4.3l, 1992-05 jimmy v6 4.3l, 1985-86 k1500 v6 4.3l, 1988-98 k1500 v6 4.3l, 1985 k2500 v6 4.3l, 1988-95 k2500 v6 4.3l, 1990-99 p3500 v6 4.3l, 1987 r1500 v6 4.3l, 1987 r2500 v6 4.3l, 1988-90 s15 v6 4.3l, 1988-91 s15 jimmy v6 4.3l, 1985-05 safari v6 4.3l, 1996-13 savana 1500 v6 4.3l, 1996-05 savana 2500 v6 4.3l, 1999-13 sierra 1500 v6 4.3l, 2007 sierra 1500 classic v6 4.3l, 1991-04 sonoma v6 4.3l, 1987 v1500 v6 4.3l, isuzu - 1997-00 hombre v6 4.3l, oldsmobile - 1991-94 bravada v6 4.3l, 1996-01 bravada v6 4.3l, pontiac - 1986 bonneville v6 4.3l, 1986-87 grand prix v6 4.3l, 1985-86 parisienne v6 4.3l
