high comp heads(#62) on stock 400
« on: August 05, 2006, 02:35:43 AM »
planning on useing #62 heads  2.11 & 1.77 valves  on my 1976 pontiac 400 4-speed car    running flat top pistons with valve reliefs and chamford edges  any idea on compression  useability with pump gas? what cam would be good with stock springs  want to maximise use of 72 cc heads  the intake is from a 1978 t/a with no emissions (e.g.r.) and stock carb  with headers  also have a good set of 6x #8 heads for sale in order to pay the machinest for the #62 heads
  Thanks Ron
