Application / fitment

The kit is universal for engines using eight 1/4-20 valve-cover bolts. Confirm hole count, thread depth and cover-flange thickness before purchase.

• part type: valve cover bolt kit
• cast-aluminum valve covers with thick mounting flanges
• selected V8 engines requiring a total of 8 bolts
• custom and performance applications using 1/4-20 UNC threads
• not for applications requiring a different bolt length or thread
• under-head length: 0.812 in / 20.62 mm

Check the depth of every threaded hole so the bolt does not bottom before clamping the cover. Seat each washer flat against the flange. Tighten the bolts evenly using the low torque appropriate for the cover and gasket.
