The Biggest power gains for your 400-430-455 engine are with TAs 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 TAs aluminum cylinder heads will continue to out perform more popular engine makes.
