Re-designed Edelbrock performer heads?
Has any one heard anything good about these redesigned heads. Any flow#s out there?

I've been wondering the same thing.
Have they redesigned the Centerbolt Performer heads too?? Or did they get left since most people buy the regular versions?
I guess we'll have to keep watch in Chevy High Perf for another Flow To Go article.

Supposedly better ports for more flow. Not bigger ports, just reshaped ones.

I believe they also updated the combustion chamber design as well.

Thanks for the reminder. That's right the chambers are supposed to be shaped better and have the spark plugs relocated for more effecient combustion.

Would be nice if some one had these flow tested against the older ones to see if there really is any improvement.
