I'm setting up a plan to cam my 2004 GTO and would like some help to make sure I don't damage anything by running too high lift.
Can anyone tell me if there is enough clearance to run this setup?
BTR Stage 3 cam ( 231/242 .617"/.592" 112+2)
BTR .660" platinum springs with titanium retainers, standard size locator and stock guide size
And (GM) shaft mounted 1.8:1 roller rockers http://m.ebay.com/itm/GM-LS1-LS2-LS6-Shaft-Mount-1-8-Ratio-Aluminum-Rocker-Arm-System-/181989526397?nav=SEARCH)
Trying to avoid having to machine anything.
Goal is to create as much power as possible without having to sacrifice too much reliability.
I'm shooting for 425+HP on stock heads (eventually upgrading to TFS 220s) and rotating assembly before spray.
Thanks in advance!

At least that's the way I was thinking it would help.
