MACE factory ported cast iron heads are a must for anyone after some serious power

 

Heads Include:

  • Reground valve seats and valves using proprietary angles and radius
  • Back cut intake valves for increased flow
  • Acid washed and crack tested
  • Worn guides are replaced
  • New valve seals, springs, retainers and collets
  • Smooth ground finish for perfect sealing
  • Available for NA and supercharged applications
  • Fully assembled and ready to bolt on
  • Guides milled for use in applications to .600 lift

These heads feature CNC Port worked intake and exhaust runners, good for ~ .600 lift as supplied (limited by 105# springs), minimal material removed from runners to maintain velocity. Higher rate springs are available by request. Heads are resurfaced (fly cut) with less than 5 thousand taken off.We recommend a max of .030 milling and this will increase compression by approximately .5.

 

Please note: The heads are made to order so there will be a minimum 2 weeks wait once payment has cleared.
