ALERT!! SOUND THE ALARM!!..

I emailed Cometic before I ordered for my small block. I saw so many different part numbers my head was spinning. I asked what was different about the C5917 because that note j par posted, saying EQ or Edelbrock heads. I have the Magnum version Edelbrock head so I worried about getting something else.
Cometic responded saying the difference is specifically around the coolant passages to match those heads.

If these C5917 gaskets show up on time, they should be here around the end of next week. I got my fingers crossed.

On the Summit site, you get different results if you select small block LA engine family or small block Magnum engine family. I guess Cometic knows what they are doing, and Summit has decent listings.
