Here is a good example of what gains can be had using Higgins CNC ported cylinder heads. The power readings below were obtained on the same car on the same chassis dyno at HP-F.

Green is as follows:

  • HP-F Camshaft upgrade
  • HPF 3in exhaust, 1-7/8in headers
  • VCM OTR with MAF
  • HP-F dyno tune

Red is as above with the addition of:

  • Higgins CNC ported L98 cylinder heads
