I have a pair of stage 2 Ported LS6 heads ported by a local shoper here in k.c. that only does head porting. They look awesome and flowed 311 with stock valves! These are un-milled and will work with any big cam. I was running these with the ms4 and fast 90/90 setup. Went 11.6@120mph n/a through a 4l80e/4000 stall. These heads have right at 2k miles on them, I replaced them with Trickflows. They are running the PAC 1518 valve springs good to .650 lift. Im looking to get $900 out of these. Pics upon request and paypal accepted. Need to get rid of these. I will also be at the LSX Shootout if anyone wants me to bring them.
