408 twin turbo - which cathedral head? Looks like i will step up to some thick deck heads and i'm looking at a few right now but need some direction please...which brand and what size runner? Here is the combo: 408" iron truck block, pinned mains, pyramid head gaskets (andreas), twin precision 6765's, 238/243 604/612 at 115, 9.0 comp, ls6 intake and th400. More info in sig if needed.... Not looking to break the bank but want a good head that can help me max out these turbo's and maybe go larger turbo later. Also, not overly concerned with low end torque because this is a street car with limited traction down low anyway. Thanks for any help! tracy

those are some really nice heads. They are six bolt for future growth and your turbos wont care if they have a 225 235 or 245 intake runner.

Thanks outlaw!
Killer heads but it looks like i would have to change my shaft rockers and intake manifold. Correct me if i'm wrong. I might look into the ls3 intake/rockers just to give me an idea on price. thanks

It all depends on your budget. I wouldn't go ape **** with heads. With your setup you could put 317s on and still make more power than you can use. I'm running as cast Darts and have never complained of not having enough power. I have less than $1500 wrapped up in my heads including the combustion chamber work. -- just another budget friendly option.

hey sam, the afr 230 is def on the short list!
Hey nit, as usual, time is not on my side so i would prob use something out of the box.
hey frank, that is cheap! Unless i find a nearly new set of heads (used) that have already been tricked out, i'm just going to slap a thick deck set on the new motor. Thanks guys!

On a side note, i just received my Cooper Ring head gaskets from andreas in sweden. Not cheap for a head gasket but if it holds the boost, it's worth twice that amount.
