Edelbrock aluminum heads

I had a cast iron set of Js just redone for just under a grand. I hear Speedmasters are a better choice for the money but if they need machine work right out of the box I disagree. I expect something like that to bolt on out of the box and work...that's savings to me .

I got a black Friday deal on Speedmaster big block heads 900 bucks a pair! Bolt on ready? Not so much. Good quality, but assembled with no time and patience to properly get all seats to match each and every valve. I will do all of that, but if they had been run, I guarantee problems would have developed later.
