Does anyone know why the ls7 heads would not work on the ls1? I was reading another forum about it but no one said exactly why they wouldn't work. They did say it would work on the ls2 though and because the ls7 was a truck motor the heads would only cost $400 a piece.8-O With intake, cam, and throttle body THEY said you would see a 100+ horsepower gain.8-O If you changed springs and fuel rails it would be a even bigger horsepower gain.

I knew it was in the vette but one of the post in this forum said they also put it in the tahoe which was what i was reffering to...here is the forum where it was posted in http://www.ls1.com/forums/showthread.php?t=25890
is it possible to make the ls1 handle it or would it be like swapping a v6 for a v8 as far as money is concernedLast edited by chevyman9306; April 19th, 2009, 12:31 PM.

L92 and LS3 heads are the same casting, only the valves and springs are different, in stock form they flow around 332 cfm.
And yes the L92's are about $400 each fully assembled but you need a minumum of a 4.00" bore (6.0 block) to clear the intake valves, and you need the L76/LS3 passenger car intake. They are cheap because they are mass produced and are used on the L92, LS3, L76, L98 and L99
Also the LS7 heads are a step above the L92/LS3'sCraigSemi Retired Street Racer2012 Lava Red Mustang GT 5.0 MT82GONE BUT NOT FORGOTEN

But it also depends on your goals cause 400 RWHP can be had with stock heads.CraigSemi Retired Street Racer2012 Lava Red Mustang GT 5.0 MT82GONE BUT NOT FORGOTEN
