I'll do some looking thru my 55-60 GMC Parts Master book tonight and see
if I can figure this out.

Subject: [oletrucks] GMC - Large valve inliners
Does anyone out there know how to determine whether a GMC 270 or 302
head,
has the large valves without removing the head? Engine type is easy;
although if it has been swapped to another vehicle, I'm not sure how to
tell
what year it is. I believe all the 52-59 302s had the large valves, but
not
sure about the 270s.
