Default most reliable non-leaking valve covers

I was just curious to see what everyone is running for valve covers in a FI application. I have some piece of crap fabbed ones that due nothing but leak out of the valve cover gasket. It works great for a bond type smoke screen, but I'm tired of taking them off and resealing them. (not to mention the fact that they have no guides of any sort to help with the bolts so it's next to impossible to get them threaded in) Center bolt btw and I need -10 an ports for the catch can. Thanks Chris

Buy better quality ones or just use stock.

None should leak. And why arent there any bolt guides/seals ?

stock is leak proof, cheap aftermarket isn't-the cheap ones bend if you tighten them, causing the gaskets to leak

That is a testament to how worthless these covers are. They just have some Allen head bolts that thread in and the covers have a bevel where they "seal". No gaskets or guides to help align the bolt into the head. Bought em off of a member. He failed to mention any of this, but I guess for 150 bucks that is the lesson learned. I have stockers, but I'll have to tig in -10's and close up all the stock barbs. They're kinda ugly to be putting on my engine. I know function is king, but I'd like to have both.

I am running the Moroso's with the coil bracket mounts. Pricey new but worth it to not have to worry about alignment or leaks.

Lol somehow I think you have a set coming that has "baller" engraved in yours Brian. Lol
I definitely need to do something different because it basically pukes down the firewall and all over the exhaust/bottom of the car.

Granatelli had some nice billet covers on sale in the Sponsors forum here

Not overly cheap, but certainly great looking pieces

What does everyone think of the proform valve covers. The reason why I inquire about them is because on the passenger side one of the primaries comes up and actually might touch the taller style valve covers. They have a slanted type of build to them that looks like it would clear. Thanks thus far for the input and reviews on the valve covers. I appreciate the help and insight.
