Working with noted Engine Builder Tony Bischoff of BES Racing Engines (Winner of the 2006, 2007 and with a Gen 3 HEMI, the 2010 Engine Masters Challenge!) we developed our 6.1L Ported and Polished Heads & Intake back in 2006 and to this day our BES ported and polished heads are known for their record horsepower records. Available for all NA and supercharged, turbocharged or Nitrous injected vehicles, our Stage 2 ported and polished cylinder heads and intake manifolds motors are used on safe and consistant motor packages producing well over 1200 horsepower.
With back to back dyno tests of just our Stage 1 heads and intake package, we averaged gains of 45 rwhp and 44 rwt while achieving maximum gains of 49 rwhp all running cold (with airflow for cooling, approx. 180 degrees engine temp). Our heads out-performing our own expectations and with our experience of working with and installing all of the competitors heads we're extremely confident that our HHP/BES Heads will beat the competition.
Testing: circa. 2006. The factory computer takes the additional airflow without tuning, but custom tuning with Diablo CMR is highly recommended to ensure that you are safely getting all of the power out of your vehicle. Our initial testing was completed without custom tuning and utilized the stock computer tune.
Data:
Baseline Maximum Output: 365.37 rwhp / 366.17 rwt
Baseline Heat Soak Output: 349.35 rwhp / 359.36 rwt
Final Average Output: 410.70 rwhp / 410.46 rwt
Final Maximum HP Output: 413.99 rwhp / 401.33 rwtq
Final Heat Soak Output: 388.25 rwhp / 376.69 rwt
Results:
At full heat-soak (no fans and 15 minutes idling to reach 220+ degrees) we showed gains of 38 rear wheel horsepower and 24 rear wheel torque. Heat-soak numbers mean nothing since you will never run at these operating conditions but we use them to show what the absolute minimum gains are. That''s an awesome gain!
Research: Compare our ported and polished cylinder heads and ported intakes to that offered by our competitors. Not all heads are ported the same and when it comes down to it, the true value behind our record holding cylinder heads lies in the high levels of experience that BES used to design their killer port and valve job designs.
Installation at HHP (DE/SC/KS): We can also install your heads and intake for you at an awesome price, too, and from the outside you can't tell that any work has been done to your vehicle. Dealerships cannot tell unless they break into the engine. If you are unable to get your SRT-8 to us we can ship our heads and intake to you in return for your stock heads and intake - no core charges are involved! Installation requires oil change( Royal Purple & K&N Filter usually), coolant change and all new head bolts and gaskets. If you need to purchase new head bolts and gaskets (see links below), just let us know at the time of purchase.
Additional Parts Required:
Difficulty: This modification should only be done by trained professionals. Installation time is on average 12 hours and requires trained expertise.
How To Choose Which Stage Package To Go With: If you are just installing these ported and polished heads and intake without the installation in the near future of an aggressive cam then you will need our Stage 1 Heads Package. If you are installing the HHP Stage 1 Custom Cam, then you will only need to select our Stage 1 Heads Package to go with it if you choose to combine the two. If you are installing a fairly aggressive, i.e. high lift cam, such as our HHP Stage 2 Custom Cam or using these heads with a stroker motor then you will need to select our Stage 2 heads package which comes with the necessary upgrades. We use a specially designed and tested valve spring from PSI with Titanium retainers combination that outperforms the competitions valve springs. We''ve tested and broke several manufacturer''s valve springs and since this is the weakest part of the engine, we've developed a special combination that performs flawless and is extremely safe. Just select the Stage Options to add the spring combination for use with the higher lift cams. If you have any questions, please give us a call at 888-894-1115.
Notes:
-
The purchase of the ported intake manifold with your purchase of the ported heads is highly recommended for maximum performance gains.
-
Due to the extremely high value of 6.1L Heads and Intake Manifolds a fully refundable core charge is applied. This core charge is refunded upon proper return of your serviceable stock 6.1L Heads and Intake Manifold in an undamaged, complete condition. Damaged parts will be replaced and deducted from your core charge.
-
If you're interested in Kooks long tube headers, the installation time and cost goes way down if you have it done at the same time your heads are installed since installation is much easier and quicker.
-
Exterior of Intake Manifold is touched. Coating and Polishing options are available through HHP.
