Hey guys couple things I’m looking into. I purchased a set of PRC 2.5 heads that I’ll be running with my torquer v4 cam on a stock ls1 setup. I’ll be running a .40 mls gasket on a 62cc chamber. With the long duration of that cam, will I be running into a PTV issue? Also what compression will I be at? Lastly, what spark plugs do you guys recommend to run with that setup.

 

Call TSP. They'll be and to tell you everything you want to know.

I'm fairly certain you won't have PTV issues though.

As for spark plugs, if I remember correctly I went with TR55IX on my car, they'll probably work great for any N/A setup. I have the Torquer V2 and stock heads.
