Maybe. Might even run well. Carb, distributor, fuel supply, transmission, rear end gearing all contribute. We'd need more details to provide a reasoned opinion.

Re: vortec set up what u think?
bent four valve when motor blew up. and its going to cost $175 for valve job $50 for new valves, $200 for springs and stuff to take the xr276hr and need to be shaved a little. alot cheaper to fix the vortec for more lift. will i lose that much power using the vortec heads? btw planing on porting them vortec's

You have some stock casting Vortec heads laying around? Pressed in rocker studs? You'll be doing the porting yourself, I assume (haven't heard a lot of good things about self-ported Vortecs).
I'd go with Fast Burns first, maybe Etecs or other large port Vortecs, but you shouldn't lose a whole bunch of power.

I don't know how to quantify the power difference, other than it would probably be noticeable. I think I'd fix the Trick Flows.

The milder the cam, the better the Vortecs would do.
