Notes on
Heads
(£150 surcharge applies (per pair) if, for whatever
reason, exchange/return heads are not available.
Most engine's head upgrade requirements (after 1994, Serp.
Type), would need to be based on our brand new heads (see
below) in which case no exchange is required.
Our brand new heads are latest spec. 28cc combustion chamber
to allow for composite gasket use with no loss of compression,
and feature the latest 10-bolt fixing, unleaded, oil-impregnated
guides, and fully-enclosed guide seal inlet/exhaust. They
are compatible for all V8s, 1960 through 2001.

Ultimate big valve heads, For 4.8 to 5.2
capacity or serious competition.
We have used them on
engines up to 334 bhp and have seen them tested on engines up to 400bhp, indeed
my own 5.2 with these heads can produce over 403 ft/lb of torque at 2800rpm,
but I must confess we don't have the flow data to prove it (I guess we spent
too much time porting). But quite simply we believe they are the best you can
do, without starting again with a new solid block of
Aluminium.
