I got a 350 with roller rockers, and tall valve covers..... and I need to put the original carb on the truck so that I can clear smog, but the original carb hits the EGR valve because of the spacer underneath it (for the taller valve covers).... Are taller valve covers needed for the rockers?... Can I put shorter valve covers on?.... If I can put shorter covers on then Is there a way to get the carb on there???... Thanks in advance!
 
I would look at the Egr adapter , I remember Edelbrock had one , move it back and over . May work , not sure though .

Maybe stack a couple factory riser pads which came on some factory apps ( triangle base shaped ) .
 
well I know the center bolt covers will not make it with rollers, what type of rollers are these. Roller tip, shaft mounted, aluminum?
 
The rollers will fit but it depends on how tall the girdles are if you have them.

strange, i dont see where he said anything about having stud girdles. since he has to pass smog with it, its highly doubtful he has anything wild enough to warrant stud girdles.

There now you can untie your panties:wink1:
 
I don't know where folks get some of their info. No offense, just doesn't make sense.

I'm running roller 1.5 rockers under my stock centerbolt valve covers. (The super fat pro magnums at that)

However, looking at your profile, it appears you have a 1984, which would be perimeter bolts if it hasn't been changed. I don't see any reason they won't work under the perimeter style, as was already mentioned, as long as your lift or rocker ratio isn't too much.
 
Thanks for the info guys. Yes I do have an 84 k10, but the engine is out of a 85 I believe, and I didnt install the rockers, I bought and installed the engine about 5 months ago. How can I determine the make/type of rockers?
 
Maybe post up some pics?

I don't believe mine are marked any other way than the "1.5" on them, but the shape/style/color/material can be distinctive.

They will hit if you use 80's style 305 valve covers. I run cheap auto parts chromies. :waytogo:

So your 383 stock covers work, but the 305 ones don't.

What's the difference? (wasn't aware of one in stock valve covers short of the center/perimeter bolts)
 
I am running cheapie auto parts store valve covers on the 383. When I originally set/adjusted the roller rockers I used valve covers off an 81 K5 305. Cut out the centers so I could adjust with motor running. When I was all done I took off the cut 305 valve covers and could see on them where the rockers were rubbing. I could also tell the 305 valve covers were more rounded than the other valve covers. Ive used Edelbrock aluminum, Edelbrock chrome, and cheapie chrome valve covers and the all work fine. I think your good unless you try a more rounded valve cover, as most are a square design.
