Cylinder head stud kit<br />
You should consider the strength and reliability of all the critical fasteners<br />
used on your engine. Increased reliability can be obtained for mild states of<br />
tune by replacing the head studs and nuts with uprated versions. The greater<br />
strength of these studs will restrict stretching under pressure and therefore<br />
keep the head and gasket securely in place.<br />

EN24 nickel chrome moly steel studs, competition head stud kit (11 studs,<br />
nuts & washers). This special kit was developed to replace the increasingly<br />
inconsistent standard items. The studs are manufactured in selected hi-grade<br />
steel and produced to exacting specifications. These studs do not stretch, so<br />
they pull the head down, not the thread up, this vastly increases head gasket<br />
life, even on high compression engines. Special thick washers, countersunk on<br />
one side, help clamping capability and reduce thread bottoming of the nuts.<br />
The 12 point skirted nuts help to increase torque accuracy through better<br />
engagement. Note that even replacing the head bolt with a stud, only torque<br />
that stud to the factory recommended spec (25ft/lbs), the other studs can be<br />
torqued to 65ft/lbs with oil, 55ft/lbs with ARP lube.<br />

Solid rocker spacer set<br />
The spacer replaces the springs reducing side loading on the rocker arms<br />
cutting resistance and creating less drag.<br />

Uprated rocker assemblies<br />
AHT438<br />
Roller rockers are stronger than the standard set up and are designed to<br />
operate the valves with less resistance, these kits also give higher lift than<br />
standard at a ratio of 1.5:1 instead of 1.3:1. Always use with uprated valve<br />
springs and check carefully for clearance.<br />

output or reliability. It is essential that the new cam is fitted with new<br />
followers as they mate with the lobe that they run on and should never be<br />
used on another lobe.<br />
Kent performance camshafts<br />
All the Kent camshaft applications/part numbers below with<br />
the suffix ‘P’ are for the original pin drive oil pump/camshaft.<br />
If you have changed your camshaft and oil pump to either ‘Star’ drive or<br />
‘Metro Slot’, use the suffix ‘S’ or ‘M’ on the part number.<br />
To assist in selecting a suitable camshaft we have prepared a table showing<br />
their various characteristics, these will change from engine to engine and<br />
with other modifications such as carburettor or valve size. A scatter profile is<br />
where the cam timing on No. 2 and 3 engine cylinders has been altered<br />
slightly to combat the poor scavenging of the siamese port design. This will<br />
benefit both the tickover and high end performance. The effect of a larger<br />
engine is to lower the camshaft’s power range slightly.<br />
Care must be taken to ensure that installation is carried out correctly and<br />
that components all work together or you will not get the expected power<br />
Lightened and Tuftrided followers wear more slowly and put less load on<br />
high lift cam lobes, they are also manufactured with a drainage hole.<br />
Another essential is the special lubricant that must be used with all new<br />
cams, it provides vital lubrication during initial starting and protects your<br />
cam from extreme wear in its first minute of use.<br />
Camshaft accessories<br />
Don’t forget the camshaft assembly lubricant or the cam timing degree disc,<br />
you will need this to set your cam timing.<br />
