NO!!! Do know how much I'v eaten during these THOUSANDS OF VIEWS!!!

Al.

Listen, don't eat so much that you develop such a belly that you could not lean over the radiator support to change the pulleys in order to let that pup show us how it can really scoot. LOL.

I know that set up is going to really wake up soon with all the right conditions and tune even at 3900 Lbs and I don't want to be near it, especially the next lane looking like a turtle.

Hey Lee, how much weight did you save going to the stock valve covers over the cast alum. versions cos mine cracked on the outer bolt hole and figured I`d go stock steel. Also, do they seal ok being so thin? Thankxxx.......

Cast aluminum will be heavier than steel in most cases being that the rail castings and or cooling/ornamental fins on top are usually thick. They will eventually crack though since it's a casting.
Stampings or welded types are better, but.........
Man, funny enough you must have missed my say in what I've done with mine.
My covers believe it or not are the infamous thin stamped Gold or Blue aluminum anodized MOROSO covers that everyone hates.
Direct Connection also had them made.
If you look back to who knows where on this long thread, I carefully body worked the MOROSO logo flat with body hammers and a solid dolly as support from behind then went lightly in with a disc sander to get all the logo evidence off and then lightly putty and sand for a smooth stock STEEL look. (Careful with this procedure because one can easily cut through the covers skin with an aggressive disc and or pressure.)
413 Decals went on for more of a stealth look.
End results: They weigh about 2-1/2 lbs all together compared to 5-1/2 Lbs for stamped steel. Though I have not weighed them as of lately, I presume the Cast aluminum covers probably weigh in the park of 10 lbs for both.
Now mind you, I made sure that the rails were straight in the first place and used good sealing MOROSO blue gaskets and aluminum studs with (Important) aluminum lock washers and nuts to make a good non-leaking seal without having to tighten too much. Tightening these types of covers is what makes them leak hence the hatred towards them, but are Ultra lightweight.
Use of pressure spreaders on the mounting nuts keeps 'em from warping out of shape as well.

Thankxx Lee I`ll see what I can find from one of my local buddies.

TD. I'm sure a set of stamped steel covers will be lighter than the cast Aluminum that you have had. Easy and cheap to find. The Stamped anodized types are getting a little hard to find these days.
The Moroso stamped Dana rear end covers (Also ultra light) are also getting a little harder to find.
I'm still looking to find the Gold Moroso/Direct Connect anodized timing chain covers. I suspect those are not easy to seal at all, but are ultra-ultra light.

Man, you started this craze with a simple question that we all know is not so simple, don't you have an antidote handy? LOL.

I`ll see what my bud`s have that they think are junk which will be my (light) treasures and ya, I love the fact that this post still kicks thankxx to yourself and the others who`ve contributed in so many ways.

I hated those stamped alum covers.. a little to tight and they
leaked... to me, in some places I dont mind the little bit of
added weight.... I use the reverse lip MP cast covers and they
weigh a ton... I milled off the ribs and logo to help reduce some
of the weight.. but they are still pretty heavy.. BUT they dont
leak no matter how hard you tighten then... I HATE OIL LEAKS

I hear ya about leaks Mike but love the stockish look especially runnin 9`s when people think my junk runs low 11`s or high 10`s at best.................

On my SB junk I have to run the reverse lip covers.. it
was pay more for custom covers or these.. I could get these
much cheaper with my discount... then I just milled the top
off... I took about 1/2" off the top and there is still plenty
of material to mount breathers with the rubber seal(thats the
way I did the 416)... the ones in the pic I had a sealed system
due to a dry sump so it would create a vac.... this is what they
look like stock(this was for mock up)

Those are similar to my MoparPerformance ones except mine use the standard short bolt not the longer deal you have which would totally stop the tab breakage so many have dealt with.

I hear you loud and clear PB.
That is exactly why I gave 'em a try with the new type gaskets out in the market theses days to see if I could make 'em work. They do with a little bit of tightening and good Moroso blue gaskets. I do go in now and then to give 'em another half turn or so to keep things from loosening up and leaking.
I would also think that the new Superformance gaskets made/distributed by a fellow Moparts member here would work fairly well with the dreaded stamped covers.

PS: are those BEST MACHINE covers made by them or just a decal on a aftermarket custom cover?
I was just at their shop last month with my car to visit. They were surprised at me just driving in.
I was like Yo! ya'll built me a street engine for the street.LOL.

Thats just a old decal... I did the covers.. I dont deal
with Best anymore.... I knew you were coming into town
but I didnt get out to Woodward

Next time.
I do get out there in the Winter as well over the Holidays.

I head for south Texas in the winter... I dont like the
cold anymore

There are some special parts brewing in the stew that I'm fairly proud of and only cost about 50.00 dollars.
Will keep you guys posted or save as to not give away the P-ending. LOL.

Forgot to ask Lee, do HS rockers clear the stock covers? Or do you or anyone else know................

Good question. Probably not with stone stock steel covers being that they have a slightly lower profile and also have baffles underneath the breather holes.
Now with the Moroso stamped covers, my Pro-magnum roller tips rockers clear with much room.
The covers are a little taller than stock ones because they resemble the HP Direct Connection types. No Breather baffles below the breather holes neither.
I'll post some step by step flicks tomorrow if need be.

These are what my covers started out to be.
They sometimes are found for cheap even though they are not much around anymore.
If I were you, I'd see if I can find a pair to borrow to trial fit over your rockers.

Thankxx, I think the width was an issue also but not 100% sure on that.......
