It rarely makes sense to port cast iron heads these days. I don't think it even made sense back in 1998 but Steve probably needed some money so he got a few articles published. These days you just buy some Stealth heads or step up to Edelbrock or Trick Flow if the wallet is a little thicker. Cast iron heads are all 50 years old and most of them are used up. I haven't seen a customer with ported cast iron heads for at least 10 years.
