Thinking about AFR 205s, worth it for my needs?
Well, I've been eyeballing a set of AFR 205's for a while now and I think I might pull the trigger. My setup right now consists of an 03 LS6 longblock out of a C5Z, 224/224 .581/.581 114LSA cam, 1 3/4 Long tubes and BBK intake manifold, all the other assorted things like P&P TB and MAF, lid, UDP, etc. I made 422/402 with this setup (through a slipping clutch), but I don't like the throttle response right now. Since it is a street car only and I'm not looking for massive dyno numbers, does this sound like a good idea? Basically I'm trying to compliment my existing setup with a well designed smaller runner head, and the CARB EO number doesn't hurt since I'm in cali.
Is the price of the heads worth it? What should I expect to gain, and more importantly will it have the effect I'm looking for of adding a little more snappiness if I jab the gas? I'm open to suggestions, I haven't seen many heads in the 205-210cc range for sale these days.

I gained 92rwhp and 38rwtq when I installed my AFR 205s and a mild cam back in 06.

You do have 243 heads with the LS6 long block, which are better than the 241s or 853s that the LS1s used. Even so, you should still see a solid 30-35rwhp bump, not to mention the torque and power under the curve.

Hi Russ....just an FYI I will be shipping your heads and ported intake on Monday
Figured that might make your weekend
OP....The 205's are great but stock 205's like a small split on the exhaust. My ported versions work well with a single patter or small split.
Consider our tried and true 224/228 cam with the headswap.....you will be really pleased with the total package if your looking for a "driver" with alot of power and good area under the curve.

I'm looking to add a H/C Package to my car as soon as the budget allows, so right now I'm in the research phase of the project. As of now, the plan is to get a set of AFR 205's and match them to a TSP 228R Cam. I'm looking for as smooth an idle as possible and aren't really wanting to go any bigger than the 228R on 114 LSA. I also figured with the 228R being such a popular choice, it should be easy for a Mail-Order-Tune to be spot-on.
Since reading the above post concerning the information on how the AFR's like a "split" duration cam, I have a question.
My question is, would I see better performance gains with the 224/228 cam you mentioned or possibly Comp Cams XER273HR (0.224/0.230-degrees duration at 0.050 and 0.581/0.588-inch lift on a 114 LSA) over the 228/228 of the TSP 228R? I will most definitely be going with the AFR 205's, so the only question is which small/mid-size cam will compliment the AFR's to allow for the most streetable HP?
Again, I don't mean to hijack, but this is the first time I've read anything about the AFR's liking a split duration. And the fact that the info came from Mr. AFR, Tony Mamo, what better place to ask.
Thanks...

I am running that combo as well and the car definitely bolts when you just touch the gas. Bump the compression and use a thinner gasket. The tuner found he could add more timing without KR with this setup. This spring I am doing a header change to LG Pros in hopes the larger CATs and mid section will bump in a few more hp.

Peak power is of course increased, but the AFR205's are all about the power under the curve!
Last winter I removed my stock AFR 205 heads and sent them to Tony for his magic.
No other changes to my setup, the dyno clearly showed:
- Peak/rear wheel increase 15hp
- Under the curve increased throughout the entire rpm band from 15hp up to 20hp at some points
- Torque increases were about the same.
Contact Tony, AFR sells two cams designed for their heads:
224/228 and the 234/238
I am running the 234/238 in my stroked 383 block.
