1.6 ratio or keep the 1.5 on mild stroker build.

The cam is pretty small for near 400 cubes, so I'd say the 1.6 would be a good upgrade. Check geometry and correct as needed

I would run the 1.6 Ratio.

However, check pushrod clearance and geometry.

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.
