1.6 Roller Rockers
I have an 89 Formula G92 car 305 TPI 5-Speed dual cats and 3:45 gears. It needs valve seals and I was thinking about changing to 1.6 roller rockers along with new valve seals and springs. I have a few questions.
1. Will they fit with the stock valve covers?
2. What kind of springs should I get and do I need different studs?
I am getting the rockers off of a friend that is selling them with an LT4 cam everything for $125. I don't know if I want the cam.
Is this too much cam for this motor?
Thanks in advance for any opinions!

Re: 1.6 Roller Rockers
Are the lifters self aligning? Cause thats what you need. If so, the narrow rockers fit in center bolt covers. With 1.6 rockers and the hot cam, you may need to change springs. I'm not sure. Your heads will work better with that cam if you port it.
