Which Motorcraft silicone is best for the later model Ford non turbo, or naturally aspirated?I have an older Duratech 3.0 V-6. Looks like the Motorcraft TA-29,30, 31 are not the correct one. I need the High Performance RTV
TA-357 correct?

NOTE: The engine front cover and bolts 7, 8, 15, 17, 18, 21 and 22 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover bolts must be installed and tightened within 35 minutes of the initial sealant application. If the time limits are exceeded, the sealant must be removed, the sealing area cleaned and sealant reapplied. To clean the sealing area, use Motorcraft®Silicone Gasket Remover and Motorcraft® Metal Surface Prep. Failure to follow this procedure can cause future oil leakage.
Apply a 3 mm (0.1181 in) bead of Motorcraft® High Performance Engine RTV Silicone to the sealing surface of the front cover.
Apply a 5.5 mm (0.22 in) bead of Motorcraft® High Performance Engine RTV Silicone to the oil pan-to-cylinder block joint and the cylinder head-to-cylinder block joint areas of the engine front cover in 5 places as indicated.
