    Will new stock vortec valvesprings work with a 260H Comp cam?

    Everything I've read so far seems to say they will be fine, but I thought I'd run it by you all here first.

    Thanks,

    Scott

    looks like the votecs can handle ~.460 lift and the cam is .440 lift. id make sure to run 1.5 ratio rockers and youd be fine.

    now that i think about it, isn't the vortec a roller motor? if so the valve springs would be too weak.

    a new set of Z28 springs are cheap and good to .500 lift, i run these springs with a comp XE262H

    Yeah, the weakness of the springs is what I was concerned with. I don't want to start floating valves the first time I rev up past 4k

    I think the heads as is wi9ll be fine.... If you want, compare the ratings that Comp and the General put out for both....
