If used, apply it only to the side facing the head, not the valve cover.<\/p>\n<h3>Do aluminum valve covers with raised sealing areas require additional sealant?<\/h3>\n<p>The raised areas may provide adequate sealing on their own, eliminating the need for additional sealant.<\/p>\n<h3>What is the correct torque for Chevy 350 valve cover bolts?<\/h3>\n<p>Official spec charts recommend either 25 or 60 inch-pounds. However, 45 inch-pounds is also a common recommendation.<\/p>\n<h3>Does the head style affect the torque specifications?<\/h3>\n<p>Yes, torque specifications may vary depending on the head style. However, the specific head style associated with each torque setting is not provided in this information.<\/p>\n<h3>Do studs with nylon insert nuts change the torque specifications?<\/h3>\n<p>Yes, but the extent of the modification is not specified in this information.<\/p>\n<h3>What should I do if leaks persist after applying sealant?<\/h3>\n<p>Re-check the valve cover flatness or have it professionally inspected, as warped valve covers can cause uneven sealing.<\/p>\n<p><strong>Note:<\/strong> For the most accurate and up-to-date torque specifications, consult the engine manufacturer or a qualified mechanic.<\/p>\n<\/div>\n<div>\n<img decoding=\"async\" onerror=\"this.src='https:\/\/motor.elfotograma.com\/en\/wp-content\/uploads\/.\/chatgpt-image-15-abr-2025-11-09-16-p-m.webp'\" src=\"https:\/\/motor.elfotograma.com\/en\/wp-content\/uploads\/IMG\/torque-specs-for-chevy-350-valve-covers.jpg\" alt=\"torque-specs-for-chevy-350-valve-covers\" \/><\/p>\n<table>\n<thead>\n<tr>\n<th><strong>Characteristic\/Advice\/Key Point<\/strong><\/th>\n<th><strong>Description<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Gasket Material<\/strong><\/td>\n<td>Cork gaskets are recommended for valve covers.<\/td>\n<\/tr>\n<tr>\n<td><strong>Sealer Application<\/strong><\/td>\n<td>Apply sealer to the side of the gasket facing the head only.<\/td>\n<\/tr>\n<tr>\n<td><strong>Raised Sealing Areas<\/strong><\/td>\n<td>Additional sealant may not be necessary for valve covers with raised sealing areas.<\/td>\n<\/tr>\n<tr>\n<td><strong>Torque Specifications<\/strong><\/td>\n<td>Tighten valve cover bolts to the specified torque using a torque wrench.<\/td>\n<\/tr>\n<tr>\n<td><strong>Leakage<\/strong><\/td>\n<td>If leaks persist after applying sealant to the gaskets, inspect the valve covers for warpage.<\/td>\n<\/tr>\n<tr>\n<td><strong>Torque Specifications (Small Block 350 Crate Engine)<\/strong><\/td>\n<td>25 inch-pounds (official), 60 inch-pounds (official), 45 inch-pounds (recommended)<\/td>\n<\/tr>\n<tr>\n<td><strong>Head Style<\/strong><\/td>\n<td>Torque specifications may vary depending on the head style.<\/td>\n<\/tr>\n<tr>\n<td><strong>Studs with Nylon Insert Nuts<\/strong><\/td>\n<td>May alter torque specifications slightly.<\/td>\n<\/tr>\n<tr>\n<td><strong>Recommendation<\/strong><\/td>\n<td>Consult a reliable source for accurate torque specifications.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Importance of Correct Torque Properly torquing valve cover bolts is essential for preventing leaks and ensuring optimal engine performance.
