I have the same problem being restricted to stock location. AFR 205 are like 1/8 higher which for me is a problem.
An alternative to consider is contact Ed Curtis at
www.flowtechinduction.com. He is considered one of the best cam builder and head guys around. Ed does a thing with a special CNC program and gets the AFR 185 heads [ stock location] very very close to 205's flow numbers. While at it, ask him to build you a special custom cam for $395. Again his reputation is way up there.

PS flow numbers are great but velocity is king
