With a worked exhaust port, light cleaning on the intake, a revised combustion chamber, GTP´s own valve job and fully blue printed spring heights this cylinder head is a value that can´t be ignored for potency. PAC valve springs are included. The average Hemi Vehicle with basic bolt-ons, Stage 1 heads, a mild Camshaft can see ET´s in the mid to low 12 second range with a proper tune. Low/Mid range efficiency will be greatly increased. Power can be increase in the top end with an RPM ceiling of about 5300 RPM. A GTP Stage 1 Head/Cam Combo will pass California Emissions standards while maintaining a near stock idle with only gaining a deeper exhaust note.
These cylinder heads are made for the cost conscience individual who is looking for excellent performance and efficiency in daily driving. We will provide the following:
