The upside of riding back here is no one notices me licking the windowYeah! Get your ass to the back of the bus Chevy boy!
You didn't get the 5.3L heads that everyone loves so much?

LQ4 is the lower compression 6.0 and uses the 317 head, which flows almost 300 cfm. Theres a 243 (I think) head that you are referring to that are better. As to how much, I don't know. The way I see it, it's like the intake - there isn't enough difference between the truck intake and the LS6 to justify spending the money.LS1 heads don't flow as well. The 5.3 truck heads (LQ4 I believe) flow almost as well as the heads that came on the LS6 (Z06). Most guys source 5.3 heads or spend extra money for AFRs for a stronger LS1 build.

Oh wait... I think my motor is labeled LM7.
You guys know how that falls into the scheme of things as far as heads and intakes go?
Is there an advantage to going with something other than the OEM replacements?

And I don't think there is enough gain for the price.
Ahh... Thanks. I have an 01 Burb with the LQ4

That's odd. I've always thought longtubes are the second biggest gain behind cam swaps on those...Looked through that thread and a couple of others. Doesn't look to be a very significant change with the heads. Some mild porting and a crank changes seem to be biggest deals in the power quest at the sacrifice of economy. Not a huge change in torque production though.
Also not too much mention of long tube advantages when discussing LS either. Not sure why that is.

Stage 2. My bad. All the info can be found on Texas speeds website. I was asked, I answered. I don't see the need for sarcasm. Must have missed somethingAh yes.... We'd forgotten the PRC level 2 spec. How silly of us.

I think had you used a couple more smileys I could have picked up on the sarcasm. @madmike1157 can fill you in on the proper usageOnly part you missed was that it was a joke (making it sound like everyone has heard of the porting).... LOL
It was my response to not knowing what the specific porting was. I really don't know much about the Chevy lingo.
