    Comp 16755 Lifter/Holley 241-91 Valve Cover

    Working on a 2002 Firebird TA with an LS6 block and 241 heads with stock valves and dual valve springs.

    Will the Holley 241-91 Valve cover interfere with the Comp 16755 Kit with .605 lift (total)? How about with stock cam? The Holley box says that with stock style lifters it will not interfere with .750 lift. Not sure that is a help or not since I don't know the installed height difference with the new lifters.

    If it does have an interference issue, how much? So I know what spacer to install with the covers...

    Comp says the rockers will fit under the stock valve covers, but Summit says they have had customer complaints and returns due to not fitting under stock valve covers. They recommend 1/2 in. spacers. I know that Mr. Gasket makes 1/8 in thick gaskets for the stock valve covers...maybe that would be enough?

    Thanks in advance to anyone who might have this answer!

    Regards,

    I have .660 lift springs with stock valve covers on 243 heads with stock gaskets and are having zero issues.
    My cam is also 237/244 so it's not a little cam.


    With spacers you have a leak issue if not fully seated or sealed.

    Starting to look like I will be OK - still, if anyone has tried this combination I would love to hear from you!

    Well, the 1675 rockers definitely WILL NOT fit under the stock valve covers. The 3/8 spacer will likely work. I got the ICT Bilett ones. Don't know yet if they leak.

    Never dealt with them.

    I know UMI sells a spacer as well. Give them a look.
