I was wondering how would these work on Gt40p heads with tfs spring upgrade kit..already installed. I am still running the stock cam in my 93lx. I recently installed a vortech v3sci and explorer intake with 36# injectors. Would the hp gain be worth the time and money?
Good question Jonathan. These are a great addition to any combination, however with HP gains does not give you a seat of the pants gratification. Since you are supercharged, I think the money would be best spent on getting the air in the motor with CAI and getting the air out of the motor with a great exhaust. I hope this helped you out.
