The Rapid Bronze Sleeve System is today’s preferred method of rebuilding cylinder heads. It has all the benefits required for both cast-iron heads and the ever popular aluminium heads. Aluminium heads are fragile and prone to severe warpage, therefore requiring more precision workmanship. The Rapid system we use does not disturb the head or alter inside dimensions, since we are only rebuilding the inside of the existing guide. Good alignment to the seats is assured.

We currently have four machines in operation for our head work. As mentioned above, our Mira Rapid System Machine enables us to give a three angled cut to the valve seat, making the engine more efficient. Our Sioux Machine refaces the valves to their original tolerances, for a gas-tight seal and a better compression ratio. Our Head Skimmer refaces the heads and blocks giving a clean, flat finished surface. Once assembled, we use a pressure and vacuum testing system.
