Need Valve Cover Options for 92 LT-1
It seems like after-market products for the 92 LT-1 motor are as rare as hens teeth. I've been searching high and low for a nice set of replacement valve covers (preferably polished stainless, but will settle for aluminum), but haven't come up with much. There seem to be two universal problems that I can't seem to avoid ... (1) all of the covers I've inquired about require modification to clear the alternator and (2) internal clearance is also a problem because of the height of the Trick Flow rockers on my motor. Does anyone know of any valve covers I can use without encountering those two problems?

You're not looking hard enough, Canton makes very nice fabbed valve covers for the Corvette, already notched for the alternator, and plenty of clearance for aftermarket rockers with no modifications whatsoever required:

Didn't realize you had a vette. These covers, I believe are specific to an fbody, but the have the notch for the alternator. I I have voodoo rockers, not sure how they compare to you, but I imagine I'm going to have to clearance the inside of the cover a bit. Have to wait and see.

Internal bracing can be trimmed to clear wide body rockers,not generally a height issue but width interferes with the through bolt tube bracing.
Far as physical bolting to the engine they are just centerbolt SBC covers so a LOT fits if you are willing to maybe clearance or reclock the rear of the alternator.

I think i bought a set of those Proform 141-131 for my 93 vette, and they did not fit.
Will check and see exactly what they were.
UPDATE
Yes they are the Proform 141-131, and they do not fit.

They might work on your Pontiac, but perhaps not on a 92 Vette. Let me know if you have any problems clearing your alternator. On my 92, the back of the alternator comes real close to the front-most edge of the valve cover. Also, my Trick Flow rockers are a bit larger than most. Yours might be slightly smaller. In any case, your new covers do look pretty nice. Good Luck!!!
The other options would be 93-96 Corvette LT1 valve covers (composite black plastic) but those typically run around $300 with hardware used, and are no longer made new.
Also, there are the carbon fiber ones that look super nice, but cost $500 http://www.ebay.com/itm/Carbon-Fiber-Small-Block-Cheverolet-Valve-Covers-Center-bolt-style-LT1-/221384278130?pt=Motors_Car_Truck_Parts_Accessories&hash=item338b880072&vxp=mtr
Also, are you sure your aftermarket heads don't allow for perimeter bolt valve covers as well? I know some do.

Fbody's have the same alternator clearance issue as vette's, it's just on the passenger side instead of the driver's side. If you look closely at the picture on the ebay link posted above you will see one of the covers is notched back (the one in the back in the picture on ebay, left hand side). You would simply run that one on your driver side, rather than the passenger side like fbody guys would have to.

I ground the back of my Alternator. It took all of 10 min after I planned where to ground. Had to ground down one of the regulator bolts but they are threaded into the case from the inside so the excess is pointless anyway. I run Proforms. You have to buy grommets for the holes and I run a cheap self sealing Mr.gasket oil cap http://www.summitracing.com/parts/pro-141-130/overview/

Here's mine, they're eBay junk. I added the fill, catch can fitting, and coil mounts. I'm running a low mount alt too but they're sheet metal so it would be easy to just cut a recess in it then take it somewhere and have it welded back up.

Let me take some pictures of my valve covers.
I set the cylinder head, accessory bracket, valve cover, and alternator on the engine to take some pictures.
Here they are.
