Using his years of experience with top-end engine components, Jason did his own port work on the heads. He started by welding material on the intake runner floors, essentially raising the runners by 0.150 inch. He left the cross-sectional areas alone, but changed the intake valve angle from 45 to 50 degrees. Once he was finished, the intake runners were still 360 cc, but airflow was increased from 365 to over 400 cfm. The good news is you can expect Trick Flow to carry Jason’s version of the PowerPort 360 heads in the near future.
