Default Re: Need a pair of 409 heads

I know the seller and he's a very honest guy, but compare the space between the valves on both heads. One has been machined a lot more than the other. I also wouldn't buy a set unless they came with a clean mag report.

Whether you buy 690s or 583s depends on what cam you plan to use. Don't try and use the Z-11 cam with 690s. The 583s take taller springs and you can't machine 690s for them without hitting water. (or too close to water).
