Porting Big Block Heads

AndyF said

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.

I read and reread those articles when they came out. I think the Stage 6 head was the only street type aluminum head available at the time and not a lotta "bang for the buck". I did a bowl port on a set of 346s and tried to copy the guide boss mods shown in the articles. This was in 2000-2001 for a mild 400. Shortly after I build the motor, the Edelbrocks came out. I typically wouldn't fool with old iron heads now, but a few years ago I did a quickie bowl port on some heads off of a 75,000 mile 318 that was just getting a Summit cam stab, used intake and headers.
