We 
  supply T-Type heads from Standard Leadfree to Full Race.
  We always fit the TF valves in our T-Type conversions; 36mm inlet valve and 
  34mm exhaust valve. The improved breathing enhances the performance and ensures 
  good valve seats even on heads with sunken valve seats.
  The Econotune features three angle valve seats, modified valve throats and modified 
  combustion chambers.
  Our Fast Road cylinder head is extensively modified, including thinning down 
  the bridge in the inlet port. If the Fast Road head is to be fitted in conjunction 
  with a supercharger, we also enlarge the exhaust ports. The ratio of inlet to 
  exhaust valve size is ideal for supercharging.
  Our Race heads can be fitted with much larger valves to suit the customer's 
  needs.
