You dont think, there's a reason they "wont" work?
LOL

Too many double negatives.

SBC guideplates don't have the same spacing as what is needed for LT1s. You will end up with several cylinders with skewed alignment.

Suggestions:

GM p/n 14011051 (8 needed) (good idea to check them for hardness)
Trickflow Part # 30400623-8
or adjustable guideplates

I tried the GM and the Trickflows and neither one was right for my heads, I ended up using the Isky adjustables.
I have a set of the GM ones for cheap if you want to try them.

What heads were those?

I have TF guideplates on my stock heads and they work fine.

I took some SBC's and hack sawed 90% of the way through, and spread the slot spacing as required. Then I bridged the cut with a weld and bolted them up. It seems like this will work well.

By the naked eye, the spacing looks different to me. Even a small amount is enough to make a difference.

Here is a comparison to some I had before from the old Combination Motorsports vendor. I think they were probably Comp plates. They did not align all cylinders properly. The spacing difference was also detectable in a side by side or stacked comparison to the GM plates.
