MSX Crossflow Alloy Heads
I can supply brand new MSX Crossflow heads at very competitive
prices.
All heads come complete with valves, dual springs, retainers,
studs and even special NGK Platinum-tip spark plugs! The valves have been lapped
in and the head is ready to bolt-on. As an extra "value-added" feature, I will spend some
time de-burring and smoothing out the ports from their factory finish. They can
be a bit rough sometimes. All this at no extra cost to you!
As always, if and when you decide to buy
from me, you will not be left alone. I will help you get the most out of the
product. This will mean tweaking the carburetors, jetting, timing and so forth.
You will have full support - until you are happy - throughout the process. You
just keep in touch and we will do it together.
I have quite extensive experience of crossflow heads for
B-series engines, as I run this setup in both my road-car as well as my
race-car. The road-car has an original HRG Derrington head from 1962. A real
beauty!
You can expect a significant increase in horsepower, just by
bolting on a head like this. but for best performance, you should also change
the camshaft to one with longer duration and higher lift, in order to take full
advantage of the better breathing capabilities of a crossflow head. Other
advantages of these heads include significantly cooler running, higher
compression without pinging (thanks to the cooler combustion process).
The current price for a complete head, as described above, is
$1100 US Dollars.
Other items that you may want to consider:
-
Brand new Weber 45 DCOE: $450 a piece
-
Crossflow camshaft with Nitrated lifters (followers): $450
-
Intake manifold for dual Weber DCOE (40/45/48), port-matched and
bolted on: $350
-
Soft mounts and linkage: $150
-
Roller-tip rocker arms at 1.5:1 ratio: $600
You can also order a "bare" head, if you whish to use your own
valves or work on it yourself. Ask for price!
Here are some pictures of both my crossflow B-series cars:

HRG Derrington head in roadcar
I am using a set of SK Racing 40mm carbs for this setup. Basically, the SK Racing carbs were Japanese copies of Webers, with some added feaures. They are no longer available. It is better to use smaller carbs for a road application, where you want low-end torque and fuel-economy. the choke size is what matters. I am using 32mm in these, so I could have used 45 DCOE with the smallest chokes... |
