TA Performance Product 3

Stage 1 Street Eliminator: TA’s Stage 1 Street Eliminator (SE) series heads are the easiest way to upgrade to aluminum heads, these heads are perfectly suited as a direct replacement for iron heads. Intake and exhaust flow are improved to out perform ported iron heads. Because these heads incorporate all of the same exterior features as stock iron heads there are NO additional parts needed when upgrading to TA’s Stage 1 Street Eliminator Cylinder Heads!

Stage 1 Track Eliminator: TA’s Stage 1 Track Eliminator (TE) 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.

Stage 2 Street Eliminator: TA’s Stage 2 Street Eliminator (SE) series heads are based off the Stage 2 iron head developed by Buick engineers, and refined over the years through almost 20 years of experience. The modified exhaust runner, or lack of, is the secret to this head. By eliminating the dog leg style exhaust runner, spent exhaust gas is sent directly into the header tube resulting in quicker flow and more volume from the exhaust port.

Stage 2 Track Eliminator: TA’s Stage 2 Track Eliminator (TE) series heads again as with the Stage 1 TE heads, have the Stage 3 intake runner incorporated into the Stage 2 heads, producing one of the most powerful cylinder heads in the performance market. These heads were bred on the track but are also the perfect head for the ultimate street/strip combination.
