Roller rockers and stock valve covers?

Is it possible without spacers?

I want to run either stock 283 or 327 valve covers. Or Cal Custom finned jobs or old Vette covers.


Those are the only covers I would ever run on any small block. If I have to I will change the rockers and the cam.

 

If you can find a set of Cal Custom covers that are the taller style with more fins, they will clear rollers. The only drawback to these covers are they have holes in them..

I was going to run the vette covers on my 57, but like you i'm running full rollers on my mill and they were nowhere close to clearing. I had a set of the Cal Custom's i mentioned above laying around and they clear with about 1/8 clearence between the baffle and the polly lock..
If i didn't have these laying around, i'd probably spring for the spacers even though i'm not crazy about em..

The new Edelbrock finned covers are tall enough.

 

...it depends on the type of roller rocker you have. Here I'm using Comp Cams Magnum roller rockers with screw-in studs and guide plates with poly-locs. I had to put double gaskets on the valve covers to clear everything, but it works. If I left off the poly-locs and ran stock nuts, I wouldn't have to run double gaskets. You can't run Crane racing-type roller rockers with Cal Custom valve covers unless you use a spacer.

 

What's wrong with the spacers?

 

heh,sure you can. as long as you are running dart heads! (the valve cover lip is raised 1/4 inch.)
run the spacers and make bigger power. form over function is for high heeled shoes,not hotrods.

 

I ran a set of finned aluminum Corvette covers on my 327 w/ roller rockers. I used two sets of cork gaskets and I had no problem with clearence.

 

...they're kinda ugly, and stick out like a sore thumb...

 

Even if you paint 'em to match the head?

 

Trickflow has someheads with raised lip too............

 

This is what I'm running as well. Using the nuts that came with the rockers. But these are roller tip only.
