All the fuel and air your engine consumes passes through its cynlinder head - twice. Improving the flow is a sure-fired way to increase output, so we strongly recommend fitting a gas-flowed head, even if your intention is a basic cylinder head overhaul.

Cylinder heads are normally supplied on a like-for-like exchange basis however, we are able to supply from stock with a surcharge, refundable on receipt of your old head in servicable condition - undamaged, complete with cam bearing caps, valve gear and suitable for rebuild.
Valve guide wear, over a period of time, damages the valve stem oil seals, allowing oil into the combustion chanbers and increasing oil consumption. When this happens, you'll notice (and smell!) a smokey exhaust and, on post '85 hydraulic engines, hear excessive rattling from the head after cold starts. This is the time to fit a rebuilt head as merely replacing the valve guide seals, a 'cure' sometimes suggested, will not work. After a short while, the new seals will suffer the same fate as the originals and your engine will smoke worse than ever.

Fit a TSR rebuilt head and you should enjoy a further 100,000 trouble-free miles.
