If you can afford it AFR's or Trickflow kick ass.If you are on a budget you really can't beat patriot heads.Everybody that I have talked to that have Patriot's,love them.Prc's are also good on a budget too.
Patriot heads are really good heads for the money.You can spend more but they are a great bang for the buck.
x2. For a budget head they are nice. I had them on my car when running a STS turbo. There are definetly "better" heads (Trickflows come to mind), but those are considerably more expensive. BTW, my HP #'s with Patriot LQ9 heads (9.0 to 1 CR) are in my sig.

I can't complain... bolt on M6, F14, PP LS6's milled to 59cc netted me 434rwhp/396rwtq SAE through Ram Twin Disk and 10bolt with 3.90's. On a 130rhwp shot it made 564rwhp/585rwtq SAE. Slipping the clutch to a lazy 1.86 60' I ran a 11.13 @ 130.9mph. Only weight reduction was spare/jack and rear seat.
Hope that helps
oh, the heads flowed 298cfm after being milled on PP's bench. I could post up the flow sheet if you need.
Does anybody know how much of a gain you might generally see between the regular heads and then heads that have been worked a little. Im not really sure what is involved when heads are "worked".
