Indy Edelbrock heads

Sorry to hi-jsck this thread but I too am interested in these 'Indy' edelbrock heads. I understand the pushrod tube has been relocated and they use offset rockers on the intake side. Do they use the W2 rockers or is it less of an offset than the W2 heads? Are they brand specific and have to use the Indy rockers? Anyone have any 'out of the box' flow numbers for the Indy VS edelbrock heads as a comparo ? That would settle the question for a whole lot of us. Please advise and thanks,
Terry
