Will these valve covers work for a stock LT1?

Alternator might hit the front of the passenger one, but not by much

Any suggestions for making it fit if its tight?

somewhere on this interweb is a guide on how to do it, you basically have to trim a part of the altenator housing with a dremel or such

It's a std short cover, it should just bolt on.

But it appears it's missing the notch in the front of the passenger side that the stock LT1 cover requires to clear the bottom/back of the alternator.

I don't remember the stock covers having a notch, I run the "tall" 141-131 Proform covers and they're not notched. Massaged the alt a bit. Others have used the same covers also.

There's a notch on my 94, and a "search" will turn up numerous posts on other LT1 sites discussing the issue with the "notch". Take a look at what Canton did to allow their aluminum valve covers to fit with the stock alternator.

Yep, they have a notch for the alternator to clear. The Proform covers will fit but you may need to disassemble and clearance the back of the alternator just a little bit.
