Product Description
Triumph TR6 North American Model Engine - Cylinder Head
North American Specification Cars
Due to the increasing concern over public welfare with regard to traffic, extensive lobbying with regard to the environment and sheer concern over safety, American legislation has often led the world in attempting to improve all aspects of motoring use. For these reasons, there are a number of aspects about the TR range which are peculiar to North America alone. While many of these local differences are catered for elsewhere on our website, some components have a special relevance and have been included or highlighted here for the benefit of our North American customers.
The original brief for this project was to create the definitive European specification website catalogue for TR6 models and highlight the major components that were different in a separate North American model section. However as time went on and where it was deemed significant to include in the main catalogue sections (the lamp, chassis, body, trim and paint sections are fully world specification) but where it would have required a new section (as in the case of carburettors and emission controls) or where room did not allow it was decided to include significant items on this page as a reference.
Please use the information on this page in conjunction with the main body of the website catalogue and if you require something for your North American model that has made its way into Europe that we don't list, please contact us.
Due to increasingly strict environmental legislation, North American engines were altered to reduce exhaust emissions and this included the use of decreased compression ratios.
CYLINDER HEAD REBUILD KIT
Identifying which cylinder head is on your engine should be fairly straight forward. It could conceivably have a later TR6 item fitted and you will need to identify which head it has before ordering a cylinder head rebuild kit.
The cylinder head rebuild kit contains everything you need to recondition your cylinder head. We assume you will have any required machining done.
The exhaust valves in the kit are lead-free compatible.
Kit contains:
Inlet valves
Exhaust valves
Valve springs
Valve guides
Head gasket set
Valve stem oil seals
Additionally why not add some or all of the following options to the rebuild kit:
Rocker shaft
Rocker arms
