Car Craft March 2006. You should also know then that once the magazine came out, they also got deluged with an BIG onslaught of angry letters from 460 engine builders crying foul.

The REAL truth:

• That article was not written by engine builders, it was written by magazine reporters that don't know engine building. Don't believe everything that you read, falconvan.
• Car Craft is driven by advertising, and one of there biggest advertisers is Edelbrock--yes, the same company that provided the heads used in the "iron versus ported aluminum" article. Hmmmmm.
• The iron head flow numbers were so dismal that they appeared virtually as bone stock, as-cast flow numbers. Whoever ported the factory 460 iron had their HEAD up their ASS. Also, they started with "smogger" D3VE passenger car heads, while the Edlebrock head is tailored after the Super Cobra Jet head. Talk about bringing a knife to a gunfight. Nevertheless, the portwork was little more than smoothing & blending, and incidentally even the lowly D3VE heads--ported correctly--have been able to hold their own in the performance world.

If I (or any of several other 460 iron head porters) supplied the heads to go up against the Edelbrocks, that "Edelbrock sales article" would have been debunked before it went to print.
