cnc'd heads

[2003EBZO6]

would a the stock zo6 heads benefit from a cnc job from someone like texas speed, what kind of power increase could you get, worth the 700 bucks to do it?? thanks.

port job ALONE.... maybe 15rwhp
port job plus mill the heads+tune..... maybe 20-30rwhp
port+mill+tune+CAM...... 40-100rwhp

Not to steal the thread, but LS6 ported and polished milled to 62cc chambers. How much rwhp would it give.

depends on current set-up.

need more info.

Considering the same, where do you see them for 700?

Edit, oh I see, using your own heads right?

[ss~zoso~ss]

people usually only do the heads if they plan on putting a cam in, just doing the heads alone isnt worth the money

once you have that much disassembled, its not much more to upgrade to a better cam to see some true gains
