Yes, you're right, in that you need to replace the intake.   I don't think 
the 2V Performer is very highly favored for high-performance applications, 
however.   (It's probably great for a Bronco or a truck).   If you don't care about 
the engine screen, you can fit the new Edelbrock Performer RPM intake, which 
is nominally designed to work with the Edelbrock heads:

It's too tall to allow you to run the engine screen.   If you are going to 
keep the screen, there are other options available to you.   I believe Dan Jones 
recommended:

Weiand X-Celerator 351V-2V (7516)
- low rise single plane with Holley carb bolt pattern 
- ports are larger than head ports. It's essentially pre-ported and 
requires the heads be match ported to the intake. 

I think that's what he recommended to Charlie McCall, who's 351C is now 
sporting iron Aussie heads and this intake.   Given that Dan is running this intake 
on his own engine, I'd have to say it's a pretty safe guess!   One thing I KN
OW for sure, Charlie's motor is very, very strong!   If the Edelbrock head 
ports are larger than stock 2V size, you might not need to do any work to them.

Here's a direct link to a series of comments by Dan on the various 351C 
intakes available:
