Twin Cam Head Porting Packages

BLUEPRINT $275-$345

Purpose
This is the perfect package for the performance enthusiast on a budget that is just looking to improve the torque output, smoothness, and longevity of the motor. Perfectly compliments many of the bolt-in torque cams available. Works well on all stock block twin cams.

Content
This package is designed to improve on the factory shortcomings buy tightening up tolerances, improved valve seals, and a performance valve job and minor airflow enhancements under the valves.
Air flow improves by using proper seat angles / widths and or radius cuts on seats and valves. Ports are deburred under the seat. Stem protrusion is set and valve spring pressure equalized. Chambers are CCd and up to a .050 head cut will be made to adjust and equalize compression. Stock springs, valves and guides are retained.
Singh grooves added

Notes:
Twin Cam OEM 88-96” heads only,
Valve lift not recommended to exceed .575 (airflow being the issue)

Cost
99-04 $345 (includes upgrade to HD OEM Beehive springs and guides cut for .575 lift)
05up $275
If guide replacement is required add $75 for AV&V Bronze Manganese guides
No other upgrades available

STREET PRO / TQ $499-$599

Purpose
We created the Street Pro/ TQ package to satisfy the need for a high torque motor build. The goal was to fix torque curves and do that with premium long lasting parts yet still raise HP and mileage. A smaller intake valve, relative the Street Pro package 1.85 vs 1.9, and proportionally smaller port are the features that enable that to happen. Airflow is vastly improved over other stock valve size packages; high velocity is retained with high airflow averages. The Street Pro\ TQ heads offer good value by adding premium parts at an affordable price. Best suited to motors with cams up to ~240° duration and >.6 lift, stock throttle body, added compression, a good pipe and tune.

Content
This package is designed to improve on the factory shortcomings buy tightening up valve stem tolerances, improved valve seals, AV&V Bronze Manganese guides, heavy duty AV&V performance valves (1.85 Intake and 1.575 Exhaust “modified”), a performance valve job, plus porting and airflow verification on the intake and exhaust sides. Stem protrusion is set and valve spring pressure equalized. Chambers are CCd and up to a .060 head cut will be made to adjust and equalize compression. Stock beehive springs are retained. All Street Pro\ TQ heads include full specification sheets which include airflow test results. Singh grooves added

Notes
Valve lift <.600 due to valve spring limitation
Well suited for 95-107” motors
Customer: Set squish at or equal to .030” for best results
Customer: Check pistons to valve clearance adjust if necessary, we can provide service at an extra charge
*Mileage improvements can only be realized by a proper tune
