About to install a set of crane race gold SA 1.5 narrow body roller rockers on my heads....anyone have experience with these as far as install, valve cover mods needed if any, etc? What type of hp increase should I expect with these? 5, 10? Thanks in advance!

 

Effects will be minimal, since you are not changing from the stock ratio. They should fit without modification.

 

Thanks Rob, I wasn't expecting any earth shattering gains being they are stock ratio...happy to hear they most likely won't have any interference issues with the stock covers
