Port my Eddy's or Stroke to 408?

The bonusses from Aluminum (Edelbrocks) are hust too much to ignore IMO. You could spend $1450 for race iron heads. They are maxxed (and I mean maxxed to get those figures if the bench is accurate) and have a finite life span. Plus, they are heavy, and, the chambers huge with no hope for tumble or squish. I've got ported iron heads flowing in the mid 250s range pulling good power figures, but a set of stock LA RPMs will do the same, and you get a chamber you can work with, and the lost weight. I'm not a fan of bling, but once you get over $1000 for a set of iron (which is very easy to do when they are done right) you might as well go RPMs if the budget allows, and build for them in terms of piston choice and machining.
