Default LS6 vs Z06 cylinder heads

Are they exactly the same? This is probably a duh question, just wanting to be sure. If so, how much is a set of these heads box stock worth? Thanks!

That's what I'm looking for, except with Patriot duals installed unless me buying them and installing them for $250 is the way to go. I guess that shows what a deal Texas Speed has on their ported ones. Are yours the 243 casting or their LS6 "style' heads? If you have a link or contact person, let me know. Thanks

The exhaust valves on 243s off the z06 are sodium filled wereasthe $400 patriots are regular valves .That being said you can get stock 243s from patriot with stock springs for around $400 . Though ifyou are going to get duals that are another $250 might as well go for their stage 2 cnc ported heads with assembled valvtrain with duals and titanium retainers.

So no real point in trying to assemble some 243 heads with dual springs myself for $650 plus the good valves. I may also keep my eyes out for someone selling take offs.
