305 Valve Covers

[cam.man67]

My question is, will the valve covers off an '86 305 fit my 350? I have an old junk 305 sitting in my dad's '86 Silverado, and I'm curious whether these would fit right onto my 350 (which is also a 1980s engine, from what I can tell). Logic would tell me that since they're both SBC it should fit right, but I don't know for sure.

The ones that came on the truck when I got it are a "set" of hideous overstyled chrome ones that have not one, but two PCV valves (one for each bank of cylinders ). What this means is that now, when I go to add oil, it takes me 20 minutes to add five quarts of oil, otherwise it overflows out over my headers.

Thanks in advance for your answers.
