What and where to clean up Edelbrock RPM's?

If you go to the Edelbrock website and to their Power Package page they have the 60779 listed for 340-360 engines...so you would think any new information would be updated there.

I hope to pick up my completed 340 tomorrow...the shop milled my pistons down for the 60779 heads...so hopefully I will be on the road in a couples weeks.

Or is this a cart in front of the horse deal, did Edelbrock learn when they got their 340 that the 68-71's had positive deck pistons, so they created a head that was machined .060" based on the 60779?
