Will 1.6 ratio roller rockers benefit my turbo build.
Okay so I got a set of dart iron Eagle SS heads from a friend for pretty cheap. I am wondering if I should get a set of 1.5 or 1.6 roller rockers to go along with the stock cam? I think the 1.6 rockers will benefit a turbo build Because the valves can stay open longer to let more air in and more air out. I was going to get a ZZ4 cam but that fell through.

72cc 1.94 int 1.50 exh
rocker stud 3/8"
Yield 8.7:1 +/- compression ratio
