Short rockers are an option but will not work if the push rod holes have not been clearance.

What are your seat and over the nose pressures?/

I build a lot of circle track engines with 135 at the seat and 320 over the nose HYD cam and with 1.5 rockers never had an issue so far.

I do use a P-55 cam core and GM lifters with the steel bottoms.
