vortec 350 question?

I have a 350 in my 66 c10 swb with some 80's iron heads. motor is pretty much stock. 12 bolt rear with 373 posi, currently the tran is a 350 with 2200 stall. shift kit, soon will be going with a 700r4/2500 stall, power disc brakes in front/drum in rear.

Heres what im wanting to do.
I want to put some vortec heads,
edelbrock rpm air gap intake (1500-6500 rpm),
maybe a 280 comp cam (280/280, Lift .480/.480, ls 110)
keep my edelbrock 600 since i already have it and its brand new and mostly used for a street rod but want a mean sound and a good kick,
also running long tube headers 2.5" pipe with super 10 flowmasters.

Now ive read to run a .480 lift i will need to cut the valvegiudes, upgrade springs, retainers. but how much do i need to cut? also can i use the stock rocker arms and push rods or what would i need to replace them with?
also anybody ran this cam. how does it do?
heres what makes me want this cam- http://www.youtube.com/watch?v=ogqSebstldQ i have also thought about a thumper cam but heard it will mess up your vacum.

If its not a drag car run these, they are working great for my street car.


I ran them with a 501. 509. Howards Cam Roller in a roller block with factory roller hardware. Really happy with how it runs and sounds.

The retainers are noticably shorter than the OEM vortec ones, (ghetto grind Mod)

If you are confortable drilling and tapping order the stock Roller hardware and retro your old block. Howards has a cam kit with lifters for something like 250.

well summit sells a cam kit with the 280 cam, lifters, springs, retainers, locks and doubel roller timing chain for $335 so if i go with this cam i would rather just buy the kit since its everything needed for a good price.
