Grant, try this website:
http://www.hardtopracing.com/articles/tech/gmcnumbers.htm  It has casting
numbers for the GMC 6 cylinder heads. According to Patrick's Chevy/GMC 6 cyl
catalog, page 8, he says the following: 2193417- Legendary "H" head, used
1950, and 1951-52.With large 1 3/4 intake ports.(I think only up to and
including 270, but not real clear) See the casting website.  2193983 "302"
head, big ports, D chamber. 52-59. 2194819 Small ports and small chambers used
on 248's and 270's. I'd recommend you get one of Patrick's catalogs. His
e-mail is patstrks@aol.com. They're pretty speedy on getting their catalog
out. Bob K in PHX
oletrucks is devoted to Chevy and GM trucks built between 1941 and 1959
