1. Install stainless steel lines to headers.
2. Install headers on engine.
3. Make sure there is no thermostat in the housing or any other type of
water temperature control.
4. Install "T" stainless steel control valve in one line of the two lines
on the thermostat housing. Connect the "T" end to header. Lines
to headers should be approximately 2 feet long.
5. The other line from the thermostat housing is your by-pass line.
Run it overboard with a 1/2" brass plumbing type gate valve.
6. The gate valve is necessary so that you can regulate the amount
of water you discharge. It also is to regulate what RPM your water
is injected into the headers. Example: gate valve is wide open and
water comes in at 3000 RPM. To make the water come in at 1500
to 2000, close gate valve approximately 1/3
