I bought new edelbrock heads last year and the ALL the bolt holes are dry. I know this for a fact because I removed the headers without draining the coolant and I do not run any sealer on the bolts either.
I had to check and make sure about this, and YES, it is true that Edelbrock heads have DRY exhaust bolt holes. I just now looked at mine and it is clear they are dry! Don't know what kind of Eddy heads GMachineDartGT has...
