Edelbrock Victor Series Race Cylinder Heads or Trick Flow cylinder heads

Have you checked to see if Edel & TF are available? So much is on B/O.

Personally, I would not spend a heap of money on alum heads for a 318.
Because when all the $$$$$$ have been spent it is still only 318 cubes.......
Money better spent on a stroker crank &/or bigger engine where you will definitely be able to feel the $$$$$ you have spent.
