Head Delima: Head Guru's Please Read!
 
I have found 3 sets of heads they are all pretty good deals i think but im not sure which set is the best. What are your guy's opinions. My mods are in my signature and i plan on doing a small mild cam later on down the road but not anything to soon. I would like to buy the set of heads that im going to see the biggest performance increase from even if i would have to mill them or do some other kinda machine work to them. But what are your guys' thoughs? Thanks in advance!!!!!!

*EDIT*
And if it helps here is a link to stock LS1 head flow numbers and some other information here, http://www.smokemup.com/tech/ls1.php. Also here is a link to Patriot Stage 3 Heads, Patriot Stage 2 Heads. I Guess you could do some comparing between them and stuff with the first set of heads. Thanks alot guys i apriciate it!

I know your budget is $1000 bean but seriously take a look in there.

You still haven't' decided on a cam yet though. I wouldn't recommend a head till I know what kinda cam you're planning on running. If your going to run a T Rex style cam go for big flow numbers in the .500 to .600 range. If your goign to run a "baby" cam run somethign that has better flow numbers down low.
