Same ones that I have in my garage waiting to go onto my truck. I would recommend upgrading your fuel system a little bit. Lots of cam/headers guys running out of fuel up top. Even just a bigger fuel pump would do the trick. I am a big better safe than sorry advocate.

Thanks for the tip. Shud I replace the main bolts heard they dont hold up. I know the cam is rated for 7000 but not really wanting to push it that hard. Was thinking 6500. Also any recommendations for fuel pump?

I wouldn't worry bout the main bolts, but a walbro 340 is pretty standard upgrade, unless you plan on bigger need for fuel.
