You can run higher compression with the aluminum heads and you'll get much better airflow out of a set of heads that were engineered to do that over a set that weren't.

Spend the money, buy the heads. You'll be glad you did.

I think that if you can port them yourself (don't bother with polish...the improvement is insignificant for a street car) then by all means do it. If I didn't have the ability to port heads myself, I probably would not have used '70 351w DOOE heads. My heads have 1.94 and 1.6 stainless valves and they are ported extensively. The intake volume is 160cc after porting and the exhaust volume is not known exactly but they are way bigger than stock. After porting them, I spent something like $550 to $600 to have all the head work done including bigger valves, guides, guide plates, valve job, seals, decking, etc.

For a $600 investment plus the cost of the heads if you don't already have them, they'll do a nice job on a street/strip small block up to 347 ci. Lets say hypothetically your extra 16 cubes + 335 SAE corrected RWHP of my 331 nets you somewhere in the 350 SAE corrected RWHP area...your car will run really good and I guarantee you that you'll love the throttle response!

I have a post on the "home porting cylinder heads forum" about porting my heads if your interested.

If you have the money go for the Trick Flows. They have tons of room to grow with in the future should you decide to get wilder. TEA has an awesome CNC port program for those!!

Not taking anything away from Tracy's nicely done homebuilt combo....but go with the TW's over stock castings...as mentioned those heads will go along way up the HP ladder before they need replaced.

How big is your cam going to be and what pistons do you have? You can run a pretty big cam with the stock pistons or pistons that are for inline valve heads and trick flow heads. The Vic Jr heads have a lot of potential also. I think they are a very good head as well.

go with a custom cam from one of the custom cam guys. Jay Allan, Buddy Rawls, or Ed Curtis.
