Titanium Valve Level III 928 Cylinder Heads for 32 Valve S4/GT/GTS

     Level III titanium valve heads are the highest performance, most advanced cylinder heads every developed for the 928. These heads will deliver powerful street and race track performance. Not only will they improving the reliability of the timing belt and timing mechanisms, they offer unparalleled high rpm capability. Our advanced porting programs combined with state of the art valve and valvetrain components technology deliver a great performance value.

     These Level III head assemblies come completely assembled and you receive the full benefit of our accumulated knowledge in all aspects of head preparation. We install spring sets that will allow 7500+ rpm capability, installed at an optimum height and pressure to allow our optional performance camshaft sets.

     The cost of these valves new is extremely expensive, generally between $110 and $135 each, a full set costing over $3500. We have sources for these valves and component sets, the highest quality titanium valves and valvetrain parts from race engine builders that allow us to offer the components reconditioned to our customers for a fraction of their new cost. These valvetrain components are used by professional race teams that change the components every time an engine comes apart. Many of the sets that we receive have run for less than 100 miles, some are difficult to distinguish from new. None of them have any wear, and they are re-machined to fit our (or your) custom specs and they are assembled in your modified 928 heads. Please refer to our detailed write-up about these titanium valve sets and the advantages that they offer.
