So i went with the 1.6 rockers. Speedmaster had a nice black Friday / Cyber Monday sale. So i picked up a set of the stainless steel in 1.6. Jeggs rocker arm calculater shows i should see a nice little bump in lift from 462/470 to 492/501 as well as duration. It may be awhile before I get them on and running but I promise I'll try and update this thread with my thoughts after install.
Thank you all for the input.
