Patriot Dual Valve springs
#1
![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
Anyone get the SDPC catalog? On page 5 they advertise the CNC ported LS6 heads and say they come with PP's proprietary dual valve springs good to .620" lift. Is this a typo? I thought the springs were good to at least .650". I am just curious.
Thanks
Matt
