MTI Stage IIR LS6 heads FS - F-Body Road Racing and Autocross Forums

I am unloading my MTI Stage IIR LS6 heads because I am moving to a new combo on the next motor. These heads made KILLER power with an X1 cam. Dyno on a full bolt on car THROUGH A MOSER "9 was 430rwhp and 406rwtq. On a 10 bolt car that would be a 450rwhp configuration. This was also done on a CANNED TUNE! There is more there if I could have refined the tune a little better but I did not have Edit or HP Tuner.

SPECS:

MTI Stage IIR LS6 heads
Milled .030
2.055 int (Ferrea)
1.60 ex (Ferrea)
Custom retainers
ISKY double spring
Intake Port: 237cc
Ex Port: 85cc
CC: 58cc
Flowed .317 @ .600

Less than 4K miles on these heads.

One of the valves MAY need to be replaced along with the retainers and keeper for that valve. I had a rocker arm botl break and the valve tip took a couple of whacks. I will get pictures of this ASAP for anyone that wants them. If you purchase I will make sure you get a new valve if you deem nessacary or you can get it on your own through MTI.

Price: $2200 OBO. don't settle for cheap heads, you get what you pay for.
