Speedmaster 1.6 rockers

Yup, I knew they get closer to the shaft, just wasn't sure how close the push rods get with a low lift cam. Heads are on the vehicle now and kinda wondering if I'm gonna have to pull them off to open up the push rod tunnels. If so I may just change cams. Like the idea of spending less then $200 and getting the roller rockers and a little more lift as long as it's not a giant hassle
