aluminum vs. cast iron heads

Big block and you have nothing for a street/strip car - Indy areo iron $499 or Stealth Alum $899 or Eddy alum $1499 I would not buy a set of iron heads then redo them porting or not.

Small block and you have nothing for a street/strip car - eddy's alum w2 is you have big pockets for the intake and header issues related or buy reworked "J" heads that someone else took off for W2's

just my 2cents
