Will 300 valve covers fit a 350?

I just know someone here will know the answer to this one, although I doubt if it's a very common thing to do. I have some 300 stuff but I don't have a 350 around here, and if I can find one I would like it to look exactly like the original 300, green paint and all, but with more power.

 

350 valve covers are using 6 bolts, the 300 and 340 valve covers are using 4 bolts.

 

Ok, thanks.

 

I have actually considered the same thing for my 66 Skylark. I think you can get the same look using the stock 68 (and maybe 69) Buick 350 valve covers. They look very similar to the 67 300/340 valve cover and even have a spot for the 300-4 sticker for the stealth look.

Just a thought...
