Any reason they wont work?

 

nope dont think so

 

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.

 

Thanks a lot Rob


Shoot me a price.

 

I have checked the trick flow vs. comp regular sbc and there was no difference at all....

 

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

 

hmmm.

 

im running comps...no issues

 

well I had them both in my hand and stack them on top of each other...they are the same....

I used Isky before too. they are a pain in the *** b/c they move when you tighten the stud. its a pain. I just used some comps I had and they are fine

 

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.
