check out www.worldcastings.com to see their
new Rousch-tweaked iron Windsors. Should be
right up there with AFR's, TF's etc per a
dyno article I have, and I think they can be
had for around $800. If that's too much,
your next bet (if you can't find a good
used set of some kind?) would be the GT40P
explorer iron heads - they can be had quite
reasonably - look in Mustang/Ford mags. The one thing they lack is a decent sized exhaust valve (1.45) but you could maybe get
the 1.54's put in. They take a specific header to clear the diff angle on the plugs
though. Maybe GT40's?
