Complete Long Stud Oil Pan Stud Kit and Valve Cover Stud Kit
for AMC/Jeep V8's W/Serrated Flange Nuts
When it comes to oil pans or valve covers studs are the way to go and using a longer 1.5" stud is definitely the way to go if you're using a performance pan gasket such as the one piece style which are thicker. Additionally, you should be using pan reinforcement rails on any steel pan that doesn't have them built in if you don't want to have leaks from pan rail distortion and/or uneven clamping force on the pan rails/gasket. Naturally, these rails add thickness and as a result you'll either not be able to get a stock length bolt to work because it's too short or, you'll be cussing and fighting those bolts to get them started.
Don't forget - studs also make gasket installation and alignment much easier and they provide more even clamping force compared to bolts. The serrated flange nuts provided don't require additional washers and the serrations will lock the nuts in place once they're torqued.
*These may not work with some aluminum oil pans.*
