Post Mystery motor- roller rocker questions

if you saw my other post in the trannie forum you'll know i picked up a 79 short wide with a rumpidy motor that i know nothing about. so on to my question, i pulled the valve covers and found some roller rockers stamped 1.6. not sure of the make. but what i didn't like where the marks on them like they had hit the lock nuts. take a look at my picks and see what you think caused this. i've never had roller rockers before. are they on with the correct fastener or where they maybe installed wrong once. i don't get any valve train noise when it is running. watcha think?

Looks like someone wasn't paying attention when they were adjusting the rockers with the engine running. Don't those marks looks alot like the end of a socket? <img src="graemlins/nono.gif" border="0" alt="[nono]" /> <img src="graemlins/spank.gif" border="0" alt="[spank]" />

I think the more inportant question is...Where did those chunks of aluminum end-up. Is it time to check the cam & lifters, main & rod bearings and don't forget the pump. <img src="graemlins/pain.gif" border="0" alt="[pain]" /> <img src="graemlins/pain.gif" border="0" alt="[pain]" />

4X4's can be street trucks too. Just slam it, put on fat tires and when it's time to race, pull the lever and you'll launch like a rocket. With the chevy aluminum front pumpkin, the traction gains make it worth the extra 250 lbs or so.
