Right now I'm teetering on a 50/50 of just slapping them on right out of the box after spraying a little brake cleaner on them and see what they do...
I've had just about enough internet Boogeyman.. they look like beautiful heads to me and they're brand-new for heaven's sake...
And for the mild build we already know they are better than the x and J heads. Correct me if I'm wrong but a back cut on the valve, a little smoothing or an extra angle into the bowl and a gasket match would improve these heads a bit.
