Heads

The heads
are a pair of Aussie 302 heads. Similar to the blocks
we bake
and blast the heads, followed by a magnetic crack
inspection. We installed solid bronze guides and hard
seats. The valve seats get the typical multi angle valve
job. Intakes are now 2.190" and exhaust are
1.760". The valve train consists of valves by Ferrea
and other components by Manley, Comp Cams and Elgin.
After the
seats have been cut out to the new diameter, we un-shrouded the
combustion chambers around the valves.
Last step
is resurfacing the head for a straight surface and for
proper
sealing. I assembling the heads, many checks are being
done. One check shown is checking for assembled spring
height.
Completely
assembled and tested, the heads are now installed
with new
heads bolts. We pre-assemble the rocker arms and push rods
to check, valve geometry and proper push-rod length. The
roller rocker arms are a "fulcrum" style that only
requires bolting down in place. They were supplied to us
by Scorpion Racing Products and we would like
to thank them for helping us with this project. We have
used their products before and I have been very impressed with
them.
We tried
to do our home work in the cam selection. We got a lot of
feedback from other 400 owners on their favorite cam. I
also compiled a collection of cams and specs which I made a link
to. After all this, I handed the specs over to a friend at
Comp Cams and giving him the general idea of what we wanted to achieve,
he came up with a custom grind for this application. I
would like to thanks Comp
Cams for their help in the cam selection and their
donation of the cam to this project. Finally the bottom
end was buttoned up wit a custom oil pan by Kevko
Racing products.
They manufacture a rear sump pan and supplied us with a oil pump
pick-up tube. I would also like to thank Kevko for their
donation of the pan and pick-up.
