I'd make moves to round up 700 dollars.
1G Clyinder Head
1G Head, HKS 272s, 1MM Oversized Valves, Fidenza Cam Gears, Crower Springs & Retainers
$700
That is on TalonRacers or Blageos part out thread, can't remember they both have AWD black Spyders...
Built head with cams and cam gears for a good price... Can't beat that.
