Stage 1 SE Aluminum Cylinder Heads - BARE CASTING
Stage 1 SE Aluminum Cylinder Heads - BARE CASTING

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------  
    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 Street Eliminator (SE) series heads are the easiest way to upgrade to aluminum heads, and get the performance you want. Intake and exhaust flow are improved to out perform ported iron heads. These heads can be further ported for an even greater power gain, which is not obtainable with any iron cylinder head. These heads are perfectly suited as replacements for original iron heads that are cracked or in poor condition. 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! TA’s Stage 1 Series heads also incorporate the original type air conditioning mounting boss above the #2 exhaust port. 

    Fit, Finish and Function of these heads is far greater than any other manufacturer’s heads. The TA Stage 1 SE is the best value of ALL  the replacement heads. TA heads have superior machine work  and materials. TA heads come with the best quality parts,  whereas competitors heads come with inexpensive parts to lower the cost.  Each TA assembly is tailored to YOUR combination, not a generic “onesize fits all approach”!

    On 10:1 Compression engines, out of the box performance is usually 50+ HP. These heads can support pump gas combinations up to 600 HP and race combinations up to 700 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 TA 1134N 12 point nuts.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As with all TA heads, the valve spacing is improved on the TA Stage 1 Series. This allows the use of even larger valves such as 2.260” intake and 1.755” exhaust. Edelbrock Heads are limited to original Stage 1 valve sizes. The pushrods required with the Edelbrock heads weigh 30 grams more (EACH) than those with the TA heads. That’s over one pound total!
The TA Performance Difference! 

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Stage 1 SE Primary Use:

  • When a direct replacement for iron heads is necessary
  • When a performance head is desired and you have upgrade parts from your iron heads that you want to re-use such as headers, intake and/or valve train parts
  • When a performance head is desired along with some degree of stealth
  • When using a GS Air cleaner and dual plane intake combination
  • When hood clearance is a concern and where the widest selection of intakes is a benefit
  • Uses stock rockers or any roller rocker that fits a stock cylinder head
  • 60 lbs Less Than Cast ron Heads!
  • All heads have the original type bolt pattern on the end of the head, for the accessory brackets
