496 with cast iron heads or 454 with with aluminum heads ?
Need your opinion ?
My 454 2 bolt is at the machine shop right now.
Should I...........
Have the 454 machined & assembled with 4 bolt mains & 496 rotating assembly.
or.......................
Just add Dart Pro1 aluminum oval port heads & matching oval port intake.

Either option is going to cost approx $ 3,000.00. (all my slush fund)
What is the best way to go ?
What will give me the best bang for the buck ?
