Help me put "587" heads on a 318

Hmmm looks like we got a pretty wide spectrum of responses here.. from "do it" to "use something else".

Let me re-iterate, I'm on a pretty tight budget, and yeah this is mostly for street performance.. Was hoping to get out the door for $500-750, if I had to spend a grand, maybe I could justify it?. These heads are just sitting in my garage... would there be any benefit to putting these on over my stock 318 heads?

My 318 is a stock 68 2 barrel.. i was originally just going to get a edelbrock performer or weiand stealth intake for the 318 and put a 4 barrel carb on it (that would be about 500 bucks). But my next thought was how bout I freshen up these 587 heads and this LD340 intake (that I also have just taking up space in my garage) with a 4 barrel carb and see what that does to the lil 318...

thoughts?
