Notes on Heads

(surcharge applies (£POA 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.
