Default 408 help!!

Just bought my first 408 shortblock. Now i completely stuck on my heads/cam i want. I was thinking P/P LS3 heads or P/P stage 2.5 LS6 heads from TSP. My end goal is a nasty street car with hopefully a minimum of 500-550 rwhp. Any help or suggestions would be great!! Im not looking to spend the kind of money on a set of trickflow or equivalant either!

look at the l92/ls3 heads ,the ls6 heads won't flow enough for what you want to do.the l92 head has bigger valves and flows better then a ls6 head.
