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.

Can't hurt, as long as you have the PTV clearance

It usually helps on stock heads with stock cam, so those heads should also benefit slightly with 1.6's. with a turbo it could help more

Awesome!!! Cam is stock. Heads aren't far from stick lol. I hope my turbo likes them.
