Port my Eddy's or Stroke to 408?

If You Are Going 408 Make Sure Your Heads Are Not Anorexic Stock Eddy's Flow Only @ 240 @ .600 Lift. They Make Great Power Across The Board. But They Are A Little Lean On The Top End. W2,915 J,x, 587's Cut Right Will Smoke Um On The Top End With A .580 Lift Cam Or Above. Keep In Mind The Only Way Any Flow Numbers Will Help(be Realized) Is If It Is Gasket Matched And Port Matched To Your Intake. If This Is Not Done Porting Will Help Only Marginally.
