Would putting 1.6 rockers on the exhaust valves on a hobby stock gain you anything or just be a waste? Thanks

Should give you a couple more inches of vaccum.

i think you will gain some exhaust flow if your using stock manifolds and small pipes. as far as vacuum i dont know that it would help that on the exhaust side.this is all going to depend on the profile of your cam anyways. if you already have a higher lift and longer duration on the exhaust you dont want to add anymore too much kills torque and will cause over scavenging and increase exhaust temps. i suggest looking on isky cams website under tech tips and is longer exhaust duration nessisary. just my opinion.
