Default Timing Chain Question- Urgent

I've completely tore down my engine to change my cam in my LT4. I bought the Meziere Pump and Cloyes chain but now I have decided to take them back and stick with the original mechanical pump since it is brand new and 10 hp isnt really that big of a deal to me. Now the question...

I dont want the Heavy Duty GM timing chain. I was wondering if there is a cheaper yet still good chain. Is there anything special about the LT1/LT4 chain? Will this work...

OK, got the link to work. No, you can't use that timing set on your LT4.

As far as I know, if you are sticking with the stock water pump. The stock LT4 timing set or the LT4 Extreme Duty set are your only options. Look on the back of the top timing gear. There is a gear to drive the water pump drive-shaft. A conventional timing set doesn't have that provision.

Also, the Cloyes may have not worked with the 96's crankshafts reluctor ring.

You can buy just the chain for $74.00 if your gears don't look that bad. Mine didn't.

First number is the GM part number. Second one is from a place that would be the top of a mountain. Get it?

12555887

NAL-12555887

Look around, you can get it cheaper! Dam, found it for $13.77 it's actually made by Cloyes for GM!!!
