WHY ARE OUR HHP/BES HEADS DIFFERENT FROM OUR COMPETITORS?
HOW TO CHOOSE THE CORRECT STAGE PACKAGE TO GO WITH:
Stage 1 Heads (Stock Hollow Stem Valves, Springs & Retainers) 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.Stage 2 Heads (Stock Hollow Stem Valves, PSI Valve Springs, Manley Titanium Retainers) If you are installing a fairly aggressive high lift cam, such as our HHP Stage 2 or higher Custom Camshafts or using these heads with a stroker motor then you will need to select our Stage 2 heads package or higher 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. Almost every competitor of ours is new to the market in our opinion. We've been working in these HEMI engines for 8 years now and because the majority of our competitors who also sell ported heads have only been around for a couple of years at the most, they don't have our level of experience with these HEMI heads. Early on, we tested and broke several manufacturer's valve springs and since this is the weakest part of the engine, we've developed a special combination using the PSI valve spring, Manley Titanium Retainer that fits inside the stock 6.1L spring cage that was introduced by Chrysler onto these HEMI heads in order to prevent a dropped valve in the event of a valve spring failure. Our combination performs flawlessly and our use of the OEM valve spring cage makes our cylinder heads the safest on the market because a broken $12 valve spring can easily grenade your entire engine. Way too many of our competitors are unknowingly putting you at risk.
- The purchase of the matched 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.
INSTALLATION AT HHP (DE): 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:
- MOPAR Head Gasket Kit
- MOPAR Head Bolts (unless using studs)
- Oil Change & Coolant Flush
CORE RETURNS: Please mail heads/intake to the below address.

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!
