Just going off my own personal experience, yes, 1.6 RR's fit on L98 heads with no mods. I am using GMPP LT4 1.6's. They are a little pricy, but I was sure they would work which was why I chose them. The pushrod to "guide" hole clearance is a little tight, but they do not touch at all. I have heard of some people having to elongate the holes slightly to avoid contact.

Also how do you tighten roller rockers?
And do I need self-align or NON-self aligning rockers?
