Im surprised nobody mentioned the ETP 215's.
Sure, there's a 1-2 month wait for them so they're not as popular.... but those are arguably the best heads for stock cubes, too.
Not trying to turn this into another ETP vs. Trickflow thread..... but it is another option for the OP in this thread.

Jesse,
Maybe you could clear up your post a little bit for us. I think the post maker is interested in a cylinder head that will make 450rwhp easily. The customer wants easy consistant power in the 450rwhp range. The gentlemen that you questioned post provided dyno proven power gains from PRC heads that cost $1000 less than other heads in this thread. Maybe you could enlighten us with some dyno results you've had that would prove the PRC head can't produce the power the poster is looking for.
Here's the best part of the PRC cylinder heads. They make proven power for a awesome price!
How about this price comparison for you guys:
PRC Stage 2.5 5.3l heads $1200
Fast 92mm Intake & PTM T.B $1100
OR
Aftermarket Castings: $2200
Rocker Arms For Aftermarket Castings: $400+
Basically you can get a cylinder head that makes 40rwhp & a intake combo that makes 15-20rwhp or you can buy a cylinder head that makes 40-45rwhp & rockers that make 2rwhp.

You can't edit his post to say "cheapest heads" when that isn't what he said and then bring up ported stockers. You cut out the beginning of the sentence:
It looks like trickflows would be great for what you want. Give me a call or shoot me a pm and we can work out a great price for you, and give you all the additional info you need.

Yes! Me and a friend have install that setup on 2 cars in the past 2 months! Finished one up lastnight, Both off the cars got all their stuff from TSP. The last car we installed parts on got!
- TSP prc stage 2.5 5.3 heads on both cars
- TSP MS3 cam on both cars
- Long tube headers on both cars
- SLP LM catback on both cars
- ASP UD pulley on 2nd car.
- 42lbs injectors both cars
- FAST 92/92 combo for the 2nd car
- 85 mm professional product intake on 1st car and its was junk!
- Yank SS 3600 stall on 2nd car
- center force DFX clutch on 1st car.
This setup works great but I personally like the TSP torquer 2 cam better then the MS3. I have installed all the parts above on other cars also, but with the T2 cam and made around the same power, but more street friendly.
No dyno #'s on these cars yet with the MS3 cams becuase one just got finished up lastnight the auto car and on the M6 car still had the stock clutch and it was slipping on the dyno and still made 413whp, but the bad clutch with new clutch its like a new car.
The t2 cam cars put down The auto car put down 441whp and 398trq on a mustang dyno with a yank SS 3600 stall unlocked! So more around 455whp or more
-The m6 cars put down around 460whp and 402trq.

TSP qualifies for best for the money. No slander to TSP heads and I hope you didn't take it that way, I do own a set after all

I got AFR heads and I love them. I'm sure you know a lot more about heads and cam set ups than me but I didnt have to buy rocker arms. I'm sure with just a little bit bigger cam I could easily make 450. I got AFR heads because I know I will be able to save up and get a fast setup later on and have about 450-460hp and still make killer torque.

I'll tip my hand in and say that the ETP215s are a very nice head and have improved my car markedly - especially in drivability.
Our dynos read a little lower than over there, but I'm making a comfortable 395rwhp with a 224/228 cam on them and when I get some extra timing into the tune (running AFRs b/w 11.6-12.2:1 at present), I reckon it'll be up to an easy 410+rwhp - great torque too.
When I went looking for heads, I was told by a supplier (sponsor) who sells them all, that the aftermarket types, ie AFR, ETP, T/F, etc are all very good and are also within close proximity to one another.
Cheers,
Macca

6600 rpm clutch dump of death Administrator
For you HP goals I would point you towards a AFR205 and a 224/228 114LSA cam. I've seen plenty of car with this package produce very strong numbers. The port is much smaller, and has a smaller cross section than a ported stocker. Might not be the cheapest, but will defintiely do quite well.
