Taking the SE series heads another step (or two) better, the Stage 1 Track Eliminator Series heads incorporate our Stage 3 raised intake runner. The raised runner provides a more direct flow to the valve resulting in additional CFM over the standard port (SE) head, approx. 10 15 CFM on average. This design also responds extremely well to an oversized intake valve, by incorporating the 2.250 intake valve as used on the Stage 3 Series heads flow is increased considerably. This combination also responds extremely well to porting, Track Eliminator Series Heads with the oversized intake valves and porting have flowed almost 380 CFM at high lift and an amazing 340 CFM at .500 ! Please inquire about these incredible upgrades. TE heads require a raised runner intake manifold from our SP-2 series. All other features are the same as original heads and our Stage 1 SE heads. TAs Stage 1 Series heads also incorporate the original type air conditioning mounting boss above the #2 exhaust port. On 10:1 Compression engines, out of the box performance is usually 60+ HP. These heads can support pump gas combinations up to 700 HP and race combinations up to 800+ HP. Stage 1 TE Primary Use: - When high end street/strip combination is desired with a stock looking head - When Hood clearance is not an issue - When a performance head is desired and you already have headers from your iron heads PRICING Assembled $2550.00 Bare Castings $1495.00 Stage 1 Track Eliminator (TE) 480-922-6807 Order and Tech Line www.TAPERFORMANCE.com TA Performance Products, Inc. 10 V8 CYLINDER HEADS Intake Exhaust Port Configurations Rick Martinez Mahopac, NY Fastest Stage 1 Powered GS 9.25 144 MPH, 1.31 60, 3070 lbs TA Stage 1 TE heads ported, TA SP-2 Dominator Intake, TA Roller Rockers, TA Block Girdle, TA Lifter Girdle, JE Pistons, 2-1/8 Headers, etc. 780 HP @7000 RPM, 654 ft/lbs 5500 RPM Many aftermarket cylinder heads use interlocking seats because of valve spacing and the ability to use larger valves. TA Performance does not typically start out with interlocking seats for several good reasons. First off, for the average customers performance level which is a street/strip combination that usually makes peak power between 5500 to 6000 rpm, the slightly larger valves have not proven to out perform our conventional size valves. Second, is the manner in which the seats are retained in the cylinder head. Anytime you can have 360 degrees of holding surface (press fit) the seat retention is greater and much more stable. Thirdly, is the ease of repair-ability. If a cylinder head should become damaged, typically on a TA cylinder head the old seat is removed and an oversized seat is installed. Heads that have seats installed for maximum valve size (interlocked seats) would need both seats removed, the entire chamber seat area welded up and then re-machined for the new seats. Welding the seat area compromises the cylinder heads integrity because the welded area will now be soft and the new seats will have the tendency to move slightly until the weld material becomes work hardened. TA Performance can supply heads with larger seats (interlocking) for applications that WILL benefit from the larger valve size. Any machine shop can also install them for you. We have been unable to find good reason to compromise our cylinder heads, when only a few benefit from the increase in valve seat size. All of these considerations are key reasons why TA produced cylinder heads are highly regarded in the aftermarket industry. These are the same reasons why TA heads maintain excellent resale value and why heads that we produced almost 20 years ago are still in use today.
