I am getting a set of 1.6 RR, however I am not sure if they are self aligning or not. How do I tell if they are self aligning? What can I do to make them work if they are not? BTW I have a 91 stock l98. Any help in advance is greatly appreciated.

 

the area around the roller tip should come farther down then the tip itself.
if not bring them back or you could drill and tap for screw in studs and use some guide plates.

 

self aligning roller rockers have a guide or flange you could call it at teh tip were as non aligning rockers have none

I've attached images to show aligning and non(well trying anways ) gold ones are the non aligning and the blue ones are

 

the yellow ons have been changed to organe because the image was to big notise the silver roller at the end has no guide or flange

 

Hey, brian. Unless you know your heads, it's hard to say without looking. Non-self aligning rockers have guideplates that are basically a flat piece of metal with two "u's" ground in them to hold the pushrods vertical.

I haven't taken the valve covers off a SBC 3rd gen yet, do you have to remove the upper or middle to get the covers off (we have to on the V6)?
If not, just pull the covers and look real quick.

 

EDIT: Did you already but them? If so please show us...

 

Thanks john. I believe I can just take them off. I have however found out that they are non self aligning. They are actually on ebay. Cheap ones, however only temporary. Maybe you could help me install when I get them. should be in like two weeks.

oh yeah, from what i read in other posts, I do need 3/8" self-aligning ones but I could use the non self aligning ones if I got some guide plates.

 

And new studs drilled/tapped

 

That sounds pretty hard

 

Better off finding self-aligners. If you need to get those or alredy have them, I can help you chang to non's but it is a pain.

 

self aligning is ok on a stock motor. however if you are building for power i would switch to guide plates. also make sure you get the slimmer body rockers for the center bolt valve covers or you'll be screwed!

 

I heard that if you go to 1.6 RR that you have to do a little clearencing where the pushrod passes through the head. Is there any truth to this. Also, does anyone have any brand or fitment reccomendations? I have Comp Pro-Magnums on by big block and they work like a charm, but these aluminum corvette centerbolts seem harder to work with.

 

It depends on the head. Some have a narrow slot that serves as a guideplate of sorts and it doesnt leave much space for the 1.6 rockers slightly different geometry. Corvette aluminum heads have a rather large hole where the pushrods are so there's no issue there.
