Head Talk...
Head Talk... I've been on LS1tech awhile but sadly never really looked into ported heads because I never thought I would ever buy some. I know damn near everything else about our cars excpet for heads and N2O. Now I am looking into getting some heads... 
I see there are many styles, like 5.3, LS1, LS6, Stage I/II/III, 6.0, 5-angle, etc... Anyone care to explain the differences between the two.
As long as you're reading this I guess I should throw this in as well. Which heads would you reccomend to someone like me. Mods are in sig, I am a street person, rarely see the track, looking to get 430-450rwhp if possible in a relatively cheap package.
Thanks a lot!

how much power are you making now? For heads go with ported 5.3 heads for your most cost effective solution IMO. (TEA) Ported ls6 heads will make more power but then you have to pay for the more expensive cores.
You may also be able to get away with a set of AFR heads.if you are wanting 430-450 your also going to need all the supporting mods.

I made 365 rwhp without my long tubes, ported TB, ASP pulley, and on crappy mufflers. I plan to get an LS6 intake before heads, or do it all at once. I guess I'm at 385rwhp right now.
I was looking at the Absolute Speed Stg 2 5.3 heads, how are these?

I would not buy anything from him if his customer service is as bad as it looks in that thread.

After doing some reading it looks like if I buy Patriot heads the $2 valves will break and leave me with a destroyed motor. At least that the vibe that I'm getting. Is this true at all? It seems like everyone is against Patriot now becuase of a few bad cases. Anyways can't you buy new valves to replace them, or is the angle job different? I think you can relate Patriots to Pacesetter where it's risky buisness to get them. Well I love my Pacesetters and I think I would have the same satisfaction with Patriot heads. Does anyone agree or am I dreaming... Thanks

Thanks alot!
Here are the three heads I'm looking at, all from Patriot:
- Stage II 5.3, 2.02" / 1.57"
- Stage III 5.3, 2.055" / 1.60"
- Stage II LS6, 2.055" / 1.57" 59cc or 64cc
Anyone want to champion for one of these? Also what is the difference between 59cc and 64cc besides the obvious, and which one is more practical. Thanks

i have a thread goin on heads too but this seems to be more informative lol what kinda stuff would you want in a heads, how many cc, valve sizes, everything. there is so much out there to think about with heads and it just seems that most people just wanna sell waht they have in stock. just want a head that makes great power. i keep hearin about the AFR's and how they make good power and have room to work. thinking about 205's but i dont really even know lol dont know if i a ltage 2 5.3 head is better or what?!
It is hard to beat the 5.3 heads because of the smaller chamber for a stock size LS1. The compression N/A that I like to shoot for is 10.8 and the 5.3 head will easily do it. The stokers, 382/383, I like to have a 69cc chamber and a flat top piston.
