What size does a 318 (68 Coronet) valve cover bolt use? Doesn't look like a 1/4-20.

Thanks.
 
Thanks everybody.

Had one bolt that was a smaller head and when I removed it, it fell "someplace". Tried using one of the other correct bolts and it didn't seem to want to thread. Once verified, I just used a 1/4-20 stud for that one bolt. Hope this will cure the leaky valve cover.
 
I have a complete OEM valve cover bolt set (10 bolts) from a 1968 B Body 318 if you want the correct look and fit.

If you're interested please LMK.
 
I cant think of any Mopar engine that doesnt have 1/4-20 valve cover hardware.
from slant six to street hemi
