The_aSSet Posted November 7, 2011 Report Share Posted November 7, 2011 You'd need square port intake to use with those heads, either an ls3 or l92 truck intake, Offset Rockers, throttle body, x-link, etc.. But 250 is a great deal. Sent from my SGH-T989 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tylur06SS Posted November 7, 2011 Report Share Posted November 7, 2011 if you were wanting to build the motor you could piece it together, the good thing about the LS series engines is most everything is interchangeable Quote Link to comment Share on other sites More sharing options...
broke1 Posted November 8, 2011 Report Share Posted November 8, 2011 Definitely worth it!!The factory L92/LS3 heads flow more CFM than ANY fully ported factory cathedral head,hell,probably better than any aftermarket cathedral port head!!! As mentioned,youll need the l92 intake($200-$350),rocker stands($50-$60), 8 L92/LS3 intake rocker arms($80-$90),and a throttle body adaptor if u want to use your stock tb($50-$75) or a 90mm throttle body($150) and X link($225)Not a whole lot of $$$$ for the gain.You'd be best to put a camshaft in while its apart.Either an off the shelf grind used in a LY6 application(ly6=gen 4 iron 6.0 w/ l92 heads)or a custom cam from any vendor. If you decide on those L92/LS3 heads,I have a LS2Portworks ported L92 truck intake w/ rails modded to fit the "stubby" injectors used in the ls3/ls7.The intake made 17hp more than a FAST 102 LS3 intake on LME's Superflow engine dyno.I bought the intake complete from my local GM dealer and sent it to Cory for the full port job, I think I paid around $400+ shipping for the port job.Looking to get $550 for the intake w/ fuel rails and ill throw in a ported 90mm throttle body for an extra $100 if you are interested...
