Wow...
Amazing how a shop can screw up a set of heads, and claim they are done. Although you posted a table of gains, I had to put all the numbers in Excel and make this table to save, it was so amazing without a lot of trick porting. And you make a good point about low lift flow.

Also a good point about head cc's and compression ratio. The 90 cc Mopar BB heads are common, and some guys that think they have 10 CR, are way less than that, especially if their block is on the tall side, putting the pistons deep down in the hole.
