vortec heads and mother thumper cam

http://www.alexsparts.com/valve-spri...d-flat-tappet/ found these springs and thought they would be ok but just looking over cam card and dont think they will work. Dont know how to post pics so all I can do it post links. This is the cam I got http://www.summitracing.com/parts/cc...01-8/overview/ anybody have vortec heads and running this cam? I already got my vortec heads back from machine shop. Milld and machined for PC seals machined for guide plates and screw in rocker studs 3 angle valve job and new valve guides. I dont know the spec of installed height right now but I know I got alot more clearance with the PC seals

You should run this kit and shim to 130 lbs on the seat:

I don't see how it will give you any issues with the heads, it was more of a performance issue. They should play just fine together.

Look closely. You want the VSK600VFR kit, not the VSK600VFT that you linked.
It's looks like their "webmaster" has been in there editing things. The write-up under ...VFR used to say 130 lbs seat; now it states you need to shim to get to that.

Re: vortec heads and mother thumper cam

Ok I got it. I see the part number now. But instead of VFT like you said I need. Did you mean VHR?
