The other real advantage to the 401 aluminum head is you don't spend tons of time and money hunting virgin closed chamber cast iron heads. GM stopped producing the 291 cast iron head about 5 years ago, and the others decades before that. Some of them (the 291 heads) are still around for a decent price. But if you go hunting the others, you can pay $1K for what amounts to worn out junk, and as much as $3K+ for good stuff, and that's BEFORE you do a valve job and mill them. We may build a 396 over the winter, depending on how NHRA treats the combination this year. If some of the guys keep hammering it, and NHRA hits it hard, we'll just stick with the 427.
