I just installed 1.6 rr and I think something might be wrong.

Should the intake and exhaust rockers be perfectly parallel to each other?
Most if not all, of mine are somewhat nonparallel.

 

NSA or SA rockers?

 

I just finished head gaskets and using crane self aligning rockers, before and after I took heads off the rockers werent perfectly aligned.

 

Rockers are NSA.
Also, the valve covers won't even come close, to clearing the rockers.

Did I do something wrong?

 

there are some rockers than go on perfectly that you will not have problems with valve covers, with some you will, what brand of rockers?

 

More then likely you will have to modify the valve covers slightly to get them to fit under there. I just used a set of pliers and flattened the "webs" so there wasn't the little L shaped bend on the bottom and that worked perfectly.

 

pro magnum 1.6 nsa with pushrod guideplates.

 

Should fit under stock valve covers with modifying/clearencing.

 

Ditto.

 

What guideplates are you using? Some don't align well. GM p/n 14011051's do.

 

Umm, I don't know? Whatever CMotorsports gives in their kit.
Yes, they are the reason I had trouble keeping the rockers
straight. Will they be ok, this way?
Anybody have a how-to on modifying these valve covers?
I need about a 1/4" for them to fit.

 

Better centering with the GM plates. I had the CM ones to begin with.

Some good pics of valve cover modifications at the bottom of this page.

 

The LT4 valve covers don't require any clearancing. Well, unless you have Crane guideplates (I made that mistake), then you have to do a bit of grinding. The GM and Comp guideplates shouldn't require any modifying at all. I choose this route because not only do they look better IMO (especially w/ the MBA billet trim kit), they quiet down the valvetrain noise a bit.
