used set of crane gold rockers for a v-6. they were on a 4.3 and were a half 1.5 and 1.6 I traded a friend the 1.5s for his 1.6s to make it a full set BUT half is self aligning and half is regular tip so guide plates would need to be used. They are all the narrow ones that are made for center bolt valve covers. 150 takes them. you can get cheap ones for less but they will break, trust me. I only run crane gold on my cars now due to proline, harland sharp and some other brand that were cheap all either breaking or loosing needle bearings and tearing up a motor.

 

this will be fine with guide plates. add 18 rwhp to your 6 banger(got that much on a s-10)
