the article is on page 10. the heads are about 375 assembled each and the intake is 475 with 40 pond injectors and a 90 mm TB.


gmpartsdirect shows the heads at $535 list price and their price as $390, plus shipping, no core charge!!! The description doesn't say bare or assembled. It doesn't show the intake on their online site yet for comparison.

how many cfm will the lq9 heads flow stock?.. and how much power do you guys think the heads and intake are worth?.. just curious :dunno:

Stockers flow something like 246-253. If left at 72cc and with the proper tune, one might see 50-70rwhp. I'm not sure. These are flowing more than a set of AFRs I believe, and the intake out flows a FAST.


There's only one way to find out...


Does anyone have the specs of a 6.2L that these come on?
