can you simply install a 1.6rr on the stock valve train w/out doing any other mods to heads, lifters, etc... also is there any need to switch the stud size?

 

I lot of guys just install 1.6 RR's and have no issues. Others have had coil bind causing brakage of push rods. I recommend changing your valve springs to prevent coil bind. Depending on which RR's you buy will determine if your studs need to be changed; easy to do.

 

what springs would you recommend? im pretty new to all of this and need as much help as i can get

The LT4 springs work well and are low cost.
