Includes a new MLS headgasket, necessary fluids, and shop materials. Optional are ARP head studs, new water pump, and timing belt. Water pump and timing belt are recommended to be changed if they have close to or over 60,000 miles. ARP studs are recommended for anybody running higher than stock boost. This would also be an excellent time to swap cam's, intake manifold's, or turbo's since this job requires the removal of both. Price does not include extra labor required for damaged and/or heavily worn parts.
