TA Undercut Head
Studs
Background:
With only a 10 head bolt design, the Buick V8 is vulnerable to cylinder head
gasket failure under performance applications. Higher cylinder pressures from
increased compression, forced induction or Nitrous can try to lift the head off
of the block. One of the first issues that TA addressed was better head
hardware.
FACT:
Undercut head studs allow the stud to stretch when torqued to
specification, thus creating a consistent clamping load under all
hot and cold conditions.
FACT: Under cut fasteners are
trying to return to their original state (like stretching a rubber
band, the farther you stretch it the harder it pulls back).
FACT: Made from heat treated
8740 chrome moly steel.
FACT: TA Performance is the only
Buick vendor, offering this high tech fastener for the Buick V8's. |

TA 1516 - Rear Main
Seal
Background:
Neoprene seals have been available for the Buick Big Block for several years
now, however the first type available was not a direct use seal and required
trimming to fit, which can be tedious and can compromise the integrity of the
seal. TA found it necessary to offer a better alternative... thus the "No Trim"
direct fit rear main seal for the Buick Big Block.
FACT:
Much easier to install as compared to an original rope type
FACT: Direct fit requiring no
trimming
FACT: Very detailed instructions -
for the most reliable installation |

TA Roller
Rockers
Background:
Buick used a short length rocker design on their engines which made them
vulnerable when using a higher lift cam. The additional loads can break stock
rockers and/or shafts. Even some aftermarket roller rocker assemblies are prone
to breakage and accelerated wear under high performance applications. TA
Performance has a proprietary designed roller rocker assembly made by T&D.
Though T&D already offers Buick roller rockers there was still a need for a more
durable version, thus the Exclusive TA design. Our roller rockers
are another fine example of TA Performance giving you the best product
for the money.
|
FACT:
.090" wider than standard roller rockers
FACT: The rockers are first bored
.010" over the diameter of the shaft, then counter bored on each side to
house the bearing assemblies. This process leaves approximately a 5/16"
center support between
the bearings for extra strength where it is needed most.
FACT: The rockers are relieved to
clear most performance spring and retainer combinations. They can be further
machined for larger springs such as those used on roller cam combinations. The
additional .090" wider rocker with the center support makes this possible, this can not be
done with any other Buick Rocker!
FACT: 7/16" full threaded adjuster
screws allow for adjustment for best valve train geometry. Some vendors
use 3/8" which are prone to breaking.
FACT: Torrington roller bearings are
used on the SHAFT. Some roller rockers use bushings on the shaft which
are prone to walking out of the rocker. The use of bushings also
increases drag and friction which consumes horsepower and reduces the
life span considerably when compared to a rocker using roller bearings
on the shaft.
FACT: Hardened 8620 SOLID Steel
shafts
with exacting tolerances around the bolt holes ensure the most material
in vulnerable areas such as the front and rear bolt locations.
FACT: TA Rockers are made with 2024
billet aluminum that has a higher tensile strength than other rockers
that are made from 6061 material.
FACT: A Special multi stage heat
treat and conditioning process used on the adjuster screws provides the
utmost in durability & Strength.
FACT: Shipped fully assembled with
mounting STUDS as opposed to bolts, which reduces the wear and stress on
the threads in the cylinder heads. |

TA 1120 -
Main Stud Kit
Background:
Main stud kits offered by most other vendors have clearance issues with the
front section of the oil pan especially the two for the #1 cap. The TA
Performance engineering team developed a main stud kit that specifically
address' the clearance issues with the stock Big Block oil pan.
|
FACT: Accurate length ensures clearance
with oil pan
FACT: 12 point nuts for the two studs on the #1 main cap allow adequate
clearance to the front of the oil pan.
FACT: Specifically made for the correct amount of thread engagement to the
block. No threads are exposed beyond the parting line.
FACT: Made from 8740 Chrome Moly Steel, heat treated to 190,000 psi
tensile strength. |

TA
1723C - Orange Crush Head Gasket
Background:
TA Performance recognized the need for a higher quality composite
head gasket several years ago. After 15 years of negative responses from
Felpro, TA contacted Detroit Gasket. Three weeks later TA
had a prototype in their hands and within a year had a full production
run. TA Performance was able to work closely with Detroit Gasket in
the development of the Orange Crush Head Gasket, from determining
poor sealing areas to incorporating the additional head bolt holes as well
as the high performance core material. After TA had released the
Orange Crush, we were approached by another gasket manufacturer, their
engineering representative, was quite surprised to see the carbon
graphite/ steel laminate core and inquired on how we were able to get a
hold of such technology?
|
FACT:
.040" Thick Composite Material.
FACT: The only Composite gasket that
offers the four additional bolt holes for use with aluminum heads.
FACT: Uses a special cold sealant for
the ultimate seal
FACT: Developed using Fuji Film Paper
to determine inadequate sealing areas that plague other gaskets. Using
that information the gasket was modified to specifically improve sealing
in those areas, resulting in a uniform seal for the entire cylinder head.
FACT: The only composite gasket
capable of sealing up to 13:1 compression.
FACT: Uses a special laminating
process comprising of a carbon graphite core sandwiched between two steel
layers then coated with a special cold seal material. Gaskets such as the
Felpro and other off the shelf gaskets use a single steel layer as the
core, with no carbon graphite material used at all.
FACT: Only available from TA
Performance Products, Inc.
FACT: Other Orange color gaskets
available elsewhere are not the same as the TA Orange Crush Head
Gasket. |
