Nick... with the differences of SC to NA I wasn't sure on the gaskets.
Here'* my link and what I found. The coolant elbow was found as a two pack in my case at a local parts house (not a chain) that supplies local dealers etc with factory GM parts.
You will notice the elbows were made by "Help" and can be found under that part number for the SC application.
I also found uppers were seperate from lower gaskets. When given the choice of first design vs second on lower intake gaskets I had Advance get both (I'm able to send back special order...most can't) The second design came in first and I dug in.. they were a match and fit great.
Tips and tricks. If you change the hoses like I did figuring they are old and the coolant is drained, buy the tool you see in my thread. Part number for Sears is in there as well.
When gasket scraping.. go through 20 or so razor blades in your 1.99 Napa/Adavance scraper.. a fresh blade works like a champ. Soon as you notice you are working at it..change it.
Hank from RI gave me a great tip on fuel injector removal.. spray the base of each injector with silicone spray lubricant..then wiggle and pull they pop right out. Reinstall with a little vasoline on the rubber rings.
Have vacuum hose on hand.. you will find at least one that'* dry and cracked.
Other than that..I think having your bc manual in hand buddies on speed dial helps as well.
