    I am getting some brand new Dart Pro LS1 heads. They flow 315 cfm with a 580 lift, I expect to see 450-470 RWHP with a 220/224 cam. For only $1750 for the head/cam package I think it's a screaming steal.

    I went with Patriot LS6 Stage 2 Heads with the 59cc Chamber for my SLP 51013 Cam. This cam was used in a 2004 book with the same mods as my car but with the ARF heads, I actually gained 7 HP and 5 TQ more using the Patriots. Like SLP you only buy the name

    Then pay 2350 for the 225cc heads. I know a place that charges that much and has free shipping.

    What kind of Cam and induction are you planning on using? If you're not going with a supercharger I'd suggest something else if you get 92-93 octain in your area

    As far as a cam goes i am getting the TR 236/230 .602/.575 112 LSA which is obviously a BIG cam... Going to stay N/A for now and attempt to squeeze as close to 500RWHP as i can without sacrificing my DD too much then in the future (probably 1 1/2 from now) go with a stage 2 Twin Turbo setup from HP...

    They are good for 300 cfm with a 580 lift cam. They should easily produce 100 to 125 RWHP with a 220/224 cam. I already have 348 RWTQ, 375 RWTQ from a basically stock LS1. My only mods are K&N FIPK II, smoothe bellows, a Corsa exhaust and a dyno tune. Add 100-125 RWHP for the head/cam package and voila 450-470 RWHP. The Dart heads are less expensive than Patriot heads and will produce as much if not more hp than they can. They come in 205cc and 225cc intake sizes.

    You also said that for these heads and a cam package it will cost $1750!!! Are these heads are complete?? Where could i buy a set of these heads and could i use the 225cc on a street car and not destroy my daily driving??

    Well i plan on going FI but not for atleast another year or 2... I figured the 225cc intake would be too much for a N/A stock bottom end car. The gain b/t 225-205 isn't alot any way so i'm really not concerned about it. What i am curious though is the LQ9 6.0 - STAGE 3 (2.08/1.60/72cc) heads from ls1speed.com are $1195...is that the price for these heads complete or is that just for the heads them self with no other parts??

    Finally, how good are these heads?
    Are there any better for around this price?
    And how much HP should i gain with these head, a nice size cam and a tune??

    Good choice then, they come with just the patriot gold springs. check out our sponser EPP, they have a blown T/A running those heads, same price, and they don't have to ship across indiana to get to you

    No.

    First off....stock cubes I would recommend nothing more than Stage 2.
    Also, with those 6.0 heads you will lose some compression.
    And yes, those Patriot heads are complete. Good looking heads too.

    Like I said earlier....you basicly get what you pay for. The AFR's are worth every penny. I wish I had all those pennies for them.
