Alright I got a 04 z06 with ms4 cam, Kooks Long Tubes, Intake, UD pulley, and tune. I would like to get a set of Trickflows. My question is should I have the head milled? What would be the absolute best gaskets I could go with? Im looking to get the most rwhp/rwtq out of these heads so if milling is necessary I wont mind. Thanks for your help!

u prob wont be able to mill much more than maybe .015 without having to flycut which is where u are going to have the problem. they have a diff valve angle than a stock head so u would need to use the tfs head to mill and u dont want to do that as u can ruin the head. thats on a stock gasket.

I'm interested on an answer also. So I can start planning for next year.

Are you looking at a performance gain with miling?

Thats the only reason you would mill heads unless the surfaces were damaged

I had mine milled to 61cc which I was told retained stock piston to valve clearances. I could have went 59cc to bump up the compression more, but decided it just wasn't worth the worry.

where and how much was it to have them milled?

I ordered them through SpeedInc that way. The milling was added on to the purchase price and was done at TFS (extra $150 I believe).
