ok, i'm converting my L98 to 1.6 roller rockers and of course run into the dilemma of having to pay cranecams $300 for a set of narrow-body roller rockers. a ripoff i tell ya. well, i heard that there is an adapter you can buy that will convert your centerbolt heads to receive traditional perimeter-bolt valve covers. anybody know where i can find these? or at least where i could buy a set of narrow-body rockers at a reasonable price?

 

You can get an adapter by Trick Flow at summit. $99 And GM makes another but I think its about $130.

 

you don't need to go through any of that. Just modify your existing valve covers.

 

I wouldnt run the cranes. I'd go with teh comp pro mags. they fit under stock cover without mods.

 

You sure about that?

 

now i realize that the stock valvecovers need to be modified even with the narrow body rockers i believe but isn't the real issue that the standard size aluminum roller rockers won't clear the actual valve cover bolts?

 

I don't think so. I believe they have issues with the supports, not the bolts.

 

cmon guys i know somebody out there has put roller rockers on their centerbolt heads! tell me what you did and how it worked.

 

Yes they fit. Says so on their site and I run them.

 

I used to run a set of Mr.gasket rollers under the stock cover without modification.

 

You have comp pro magnum roller rockers under your stock centerbolt valve covers with no modifications?
