Our head specifications range from standard leadfree conversion to full race,
with many variations available to suit customers’ requirements.
On arrival at our unit, cylinder heads are stripped for initial inspection.
Next, they are chemically cleaned; caustic for cast iron, and acid for aluminium.
The heads are then hot washed and gritblasted.
If the head is a standard leadfree conversion, new guides are fitted prior
to fitting the exhaust seat inserts and cutting the valve seats.
If the head is to be performance modified, the next step is to reshape the
ports using die grinders- and a lot of skill and experience! When we are happy
with the modifications, guides and exhaust seat inserts are fitted and the
seats are cut, after which the combustion chambers and valve throats are modified.
The final machining process is to skim the cylinder head face to ensure it
is flat.
The heads are then hot washed, assembled and painted (if required).
Our cylinder heads are 'fully-prepared'; no assembling, lapping of valves
or fettling is required, they are ready to fit.
