Need Help! AFR vs TSP with TR224

Need Help! AFR vs TSP with TR224 I need help in deciding on which head to buy for my TR224 14LSA! The AFR 205's will work great, and leave me room for future growth, but cost a ton. They would be milled down to 62cc & I'd expect to make about 420HP peak.
While the TSP PRC 5.3's have a great price point, new cnc program, and may suit the TR224 nearly as well as the AFR's. I'll be using a Fast 92 setup with either one, and feel like the 5.3's (milled to 59cc) may only leave 10HP on the table...
The car has all the basic bolt-ons, SY3500, & is running low 12's as-is. My goal is to have a torquey street car with excellent driveability and run a few strip passes here and there. I don't really want to change the cam, since I like the setup now - just want more power/torque. Also want to get rid of the current blue-stripes on the car because they make me uncomfortable.
Ok, so this may be a question that's been asked before, but I can't find an answer that satisfies me.
Searched, but couldn't find a good comparo test. Any good advice out there?

AFR's are the amazing heads. If you are trying to save money everyone seems to get good results out of TSP PRC 5.3's. But the extra hp and torque you get out of AFR heads was worth the extra money to me. Its not just 10 hp up top its a lot more torque and hp through out the rpm's. I have a cam close to yours ill post up a bigger graph of what I got.

I have Patriot 5.3's on mine and numbers are in sig. I have AFR's on my other motors and they are above and beyond better than the ported stock castings and well worth the extra money. I would have bought AFR's in they were on the market 4 years ago.
Power is made in the heads.... Don't skimp as you will regret it later.

Thanks for the feedback! It looks like the majority is recommending the AFR setup which will more than meet my goals.
I was really considering the 5.3's, but something was nagging at me, like I wasn't making the right decision if I went with them. I'm sure they would be an improvement over the stock heads, but the AFR's sound like a significant jump over the 5.3's.
Looks like I'll be buying the AFR 205's milled to 62cc, GM gaskets, Yella Terra rockers, caddy lifters, Fast 92, & throttle body. Probably a tune also. Should be a fun summer project, I just need to pull the trigger before baby #2 shows up!
Any other results similar to the setup above? I love the motivation your results give me!

You might as well go 59 cc and the .040 cometic gaskets. less prone to detonation with the tighter quench plus more power.
11.82 scr with 59cc and the .040= more free hp

Yeah, not sure about wasting the heads -- but they would allow me room to "grow" if I feel the need for more. The comment about 59cc's is also a good one, and I'll look into that. At this point, I really wanted to stay under $3k for the parts, but can stretch to $4k or so if it makes sense.
The TR224 has a nice idle of about 750 RPM at stoplights, which enhances its driveability. I'm just not into the really lopey setups anymore, but it's still nice to hear other cars with that setup. So, I wanted to stick with the 224, avoid having to do a cam swap, and keep my project cost down. I know that doesn't make sense to everyone, but it makes me happy.
If the car runs a mid-11 after this change, keeps the 224's driveability, and doesn't break the bank for the mods, I'm ready to pull the trigger.
