EGR valve for 1990 k5 blazer question

[nbrown2500]

Want to get an EGR valve for my 1990 blazer. 5.7L stock engine. Called the chevy place and gave them my Vin and they gave me this AcDelco part number 19210641. I looked this part up on RockAuto and it says it is for a 454. The AcDeloc part number RockAuto gives is 2141432. Which one do I get and what do you guys buy in the way of EGR valves? Thanks.

Stick with delco. Check the link in my signature for the proper egr out of the gm catalog. They can/will wreak havoc if you get the wrong one.
