Head Gasket

I asked this question of Cometic through email.
They said "The part meant for the Edelbrock heads has a slightly different water jacket embossment that fits that particular head better than a standard part. I would use the C5917."

I just got mine running so I have no long term comments, but it did match up pretty well to my Edelbrock head. Mine is the Magnum version Edelbrock head. I need to find which part number I ended up using.

Page 36, post 894 on the following thread has a picutre of a C5622 from another discussion on this topic, so you can comparte to your heads:
ALERT!! SOUND THE ALARM!!..

Post 884 in that thread had a great suggestion to just call 4secondsflat, give them your application, and he will help get the correct one, which may end up as a custom part number.

I remember asking Cometic about 2-3 years ago when I built an engine which ones they recommended. They said either should work, but recommended the C5917. I just contacted them yesterday and they said the embossing is a little different but either one would work. I was able to find C5622 in stock so I ordered it. The C5917 are 5-6 weeks out atleast and I have a race in 2 weeks that I need to get the car back together for. Not really sure why the embossing would be different, same block is being used regardless so it's not like water ports and what not are moving. I'll have to compare the 2 in person to see what they differences are.
