The HD is not needed in my applications and I am putting out more horsepower in my LS92 Super Stock motor than you are in your LS1.
If you look at the application tab at Summit for the WP118 then you will see that it is for the LT1.

In most drag race only applications the WP119 will work fine. The WP119HD would help to cool the engine faster between rounds because it flows more water. But there is a trade off, The HD weights(1 pound) more and will draw a few more amps.
