Which Is The Best Aluminum Valve Cover

Hi guys,

I am going to buy an aluminum valve cover and want to buy one where I have to do the least amount of tapping or none at all. What do you suggest? Thanks

I don't think there is a best. I had a clifford and some no name and both worked great. As for drilling and tapping, it is just going to happen, so grin and bear it
ideally prep work is key, I clean it all down with brake kleen, I RVT'd my gasket to the cover, let it dry for a day after I measured and tapped the needed holes, and then RVT'd the gasket and set it, torqued it down and it hasn't leaked yet, knock on wood.

double what Bard said!

it's not so much the cover, (though you do want a decent one) the drilling/tapping is all due to the engine block.

I went with this one, which I think is GREAT deal


and if you haven't read up on changing one, the Cliff's notes are:

slightly drill out the holes in the cover for a little wiggle room, get a bottoming tap, use whatever bolts will work (use washers if they are too long, don't overtighten), you may want to put a stud in the very back hole, and do like Bard said with the gasket, and you shoud be good to go!

Good luck

Check this one out.


I've bought there Trans pan and difff cover for my Dodge. Excellent quality. I'm thinking of getting the valve cover and selling my current cast cover.

I got one off eBay and it worked OK. No matter what brand, you're going to have to tap the mounting holes on the driver side of the head. That's the hardest part...
