Cylinder heads

We undertake any machining task on many cylinder heads, including;

• Cylinder head testing and reworking i.e :-

Unleaded conversion, valve guide conversion, integral guide conversion, Colsibro guide conversion, bucket guide conversion. With valve guides we have the facility to diamond hone & to measure internal diameters correctly to give the right clearances.

• Valve spring testing.

• Cylinder head re-facing. This is done on a Rottler machine which has adjustable levelling enabling a cylinder head to be set up very quickly. All re-facing uses a diamond tool bit with which there is zero distortion.

• Hot pressure test. Especially on aluminium is a must as it opens the pores within the casting allowing you to find the leak when hot. This cannot be done when cold as cracks will not be found.

• Crack test

• Porting & polishing

• Super flow bench testing with swell & tumble facilities. This is a must in the development of a race engine. All power comes from the head & camshaft.
