ive been reading alot of the posts about the 1.8 rockers, some say get some say dont get. I dont plan on opening up my engine as this is my daily driver and i also need to tow with it. I did however aquire a set of harland sharp 1.8 roller rockers for 200 bucks. I really just need to know if i need to get better valve springs? I do have a short list of mods and i would like to finish with these rockers,3200stall,efans,and underdrive pulley. I would think i could get atleast a 13.0 out of the setup im working on. Thanks for any info you all could give me.
