how about the aussie heads? Pro Comps & Pro Toplines? they are fully CNC ported, and the 210's flow 277 on the intake and like 224 on the exhaust at .600 lift. for 500 bucks for a pair...bare of course, doesnt seem to bad. i guess figure in another 400-500 bucks for parts and labor of putting in a good valvetrain and you got a great head for about a grand. pleasse correct if people have had complaints of the quality!
