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...
