Should I Upgrade to a Billet Valve Cover? Pros and Cons?

[ciriwoh]

Hello everyone.

I'm considering swapping out my stock valve cover for a billet aluminum one and wanted to hear from others who’ve done it.

Is it mostly for looks, or are there real performance or durability benefits?

I’ve seen claims about better sealing, heat dissipation, and resistance to warping, but I’m unsure if it's worth the cost for a mostly street-driven car.

Any noticeable changes in oil control or longevity? Also, are there any downsides like increased NVH or fitment issues?

Would love to hear your experiences before I pull the trigger.

Any noticeable changes in oil control or longevity of 5.9 cummins valve cover? Also, are there any downsides like increased NVH or fitment issues?

Would love to hear your experiences before I pull the trigger.

thanks in advance for any help
