Full Flow Water Kit Option –
Using this valve cover will also allow you run our full flow water kit design that eliminates the death air pocket that can form in the upper portion of the cylinder head water jacket causing 80% of all head gasket failures and plumbs right into your radiator return line hose. After installing this water kit you’ll be able to bleed your coolant from back right of the car in a Head-Ache free area. In pictures above you can see where the water spud from this kit comes through the valve cover. This kit is also available for sale on our website (Part Number – TPR010W)

Heat Shield Modifications –
If you buy a kit with MSD coils or a full flow water kit and carry a lot of weight in your bed you might need to do some heat shield modifications. The factory beds are very flexible and extra weight may cause heat shield to contact the MSD coils and possibly ruin them.
Ignition Code Dwell Table –
MSD coil kits may experience a cold start ignition code, this is due to a variance in ignition dwell timing maps in aftermarket tuners. After a few minutes of engine running the code will usually go away. We have seen about 10% of our customers reporting a cold start code with an aftermarket tune. We have designed a new ignition dwell map that will fix this problem, any shop that has access to your tune can easily load this new dwell table into your machine.
