Mismatched Cam and Heads?

Okay that was a good answer :)
I figured I would be taking a little performance hit with a bigger cam. I was shooting for 12's this year, think its still reasonable with this cam and stock eddys? I doubt I'll have the funds to get my heads done this year. I already have the cam and lifters, so it looks like I'll find out what happens. I might be able to get another cam but I kinda spent most of my money on those shiny heads.

Looks like I'll be switching to a 3500-4000 converter, so that should help out a little.
