Can't beat PP dual springs either, and that includes Comp 921s.
Get your head out of you ***. You can get a lot less than you pay for.

Ferrea 6000 series valves, ti retainers, machined Super 7 locks, the Original Patriot Gold .650" dual springs (now used by most of our competitors)...hardly average. In summary it is sometimes hard to accept that there really are companies that strive to exceed expectations.

Guys...
Just to clarify...is this a stock displacement build?? If so I would be looking more towards our 205's (or potentially a set of smaller runner Patriots).
Also, I would be the first to tell you that the Patriot heads represent excellent value and good HP/dollar and there customer service is better than most. While I feel the AFR will make more power its not unlike most other situations where that extra power starts costing you more on a HP per dollar scenario....thats quite common actually. The key here is to evaluate carefully your own needs and objectives....if at some point in time you feel you will be looking for more, its usually much cheaper in the long run to spend the extra money up front.
No one product fits every customer....I think you couldnt go wrong either way....just take the time to carefully analyze your personal goals and your history (are you always looking for more 3 months after the last mod...etc. etc.)
Good luck...

EDIT....JUST REALIZED THIS THREAD IS MONTHS OLD....LOL

I know Gunnar and Tony, very respectable business/customer relations guys. I too believe in "theres no one product perfect for every customer", why do you think Patriot is developing their own aftermarket casting- to be more competitive in that market share. There is a place for ported factory castings and a place for aftermarkets, its up to the customer to do their homework and decide.

A couple thousand dollars can get you 150 extra hp...after that the horsepower gets real expensive. Just think, to go from 450 to 500 you will need to spend 2500 on heads and 1,000 on an intake. So you could say the last 50 hp cost twice as much as the first 150 did.

So I don't want to spend $3000 to get 475+ rwhp when I can get 450+ rwhp for $1000.
Right now the car is putting down 350 rwhp and yes that is low for the mods done to the car. So I'm thinking with the fast 90/90 setup, all of the bolt-ons and a set of 5.3 heads the car should put down 450 maybe 475 with a good tune. I think 450-475 rwhp in a 2700 lbs rx7 should move pretty good and then there is always that little blue bottle if I need to go a little faster.

PRC or Patriots are good heads, I have TSP LS6 stage 2.5. But if I had the extra $$$ to spend I would have bought the TrickFlow heads. They are making crazy HP, 500+rwhp on stock 346 bottoms.....

Orangeapeel and fellow LS1Tech users,
My name is Hank Daniecki and I am the new Director of Engineering at SLP Performance Parts. I am intimately familiar with ALL SLP parts as I have worked for SLP as an engineer for the last 6 years. SLP's engineering department will be taking a much more active role on LS1Tech and many other boards on the web to help clear up any issues or problems that anyone might have with any and all SLP products. There are many rumors and false claims being made that we want to clear up as soon as they are spotted on LS1 tech. The SLP Engineering Department loves input from customers and the challenge to make our customers as happy as humanly possible. We take our jobs very seriously. We do not like to see members bash our products that we spend long days and nights designing without solid ground to stand on. The SLP Engineering Department and I welcome with open arms constructive criticism and factual replies. I will make sure all questions are answered with great detail. Any and all on the board, please do not hesitate to email me with any issues or problems you might have. Please include in your email a phone number so that we can communicate by phone if needed. I look forward to getting SLP a better reputation on this board. Our products are top notch and we take the greatest pride in the work that we do. Please take the time to check out our website and our new 100pg catalog; I am sure you will agree our products are top notch. Also, we have re-opened the SLP Installation and Dyno Center. Please find the link below.

Thank You.

I witnessed the PP 5.3 heads tested on an engine dyno against the most popular heads out there back to back. The PP heads had more compression then the AFR 205 which were 66cc, but the PP 5.3 heads made 30 HP more then the stock heads, the AFR 205 made 40 HP, the ET 215 made 50 HP, and the TFS 215 made around 60 HP.
So I would think if you are going to spend twice as much money, you should get twice as much power.
