The Biggest power gains for your 400-430-455 engine are with TA’s aluminum cylinder heads, without question! We offer multiple cylinder heads to fit every performance combination. TA heads are cast from 356 aluminum and heat treated to T-6 specification. TA then machines the castings in house, on state of the art CNC milling machines, resulting in the highest degree of quality. TA Performance has been manufacturing cylinder heads for nearly 20 years and have gained an excellent reputation not only within the Buick community, but within the entire automotive aftermarket, for quality of craftsmanship as well as performance. Over the years, through our own testing as well as feedback from our dealers and customers, we have and will continue to update and expand our cylinder head offering. By doing so, Buick Big Block powered cars utilizing TA’s aluminum cylinder heads will continue to out perform more popular engine makes. TA Performance operates one of the few full service head manufacturing facilities in the automotive aftermarket and the only one within the Buick community

TA's Stage 1 Track Eliminator (TE) series heads take the SE series heads another step (or two) better, the Stage 1 Track Eliminator Series 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”!
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. TA’s 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.
NOTE: When using TA Aluminum heads on 400 and 430 engines, you must use pushrod oiling, i.e. 455 Lifters and Pushrods. Please inquire.
NOTE: When using head studs, you will need four of TA1134N 12 point nuts.
