Here is a site I always use http://www.mortec.com/castnum.htm

But here is your info from the above site.

3973487X...71-72...350..........1.94/1.5 or 2.02/1.6 valves, 75cc chamber

that is the best flowing stock head for a 350

that site is cool...

I pulled a set of heads off a 70's Blazer that had a rebuilt motor 15 or so years ago and set them aside never really knowing what they were. I kinda figured they were 1.94's and I checked them out on the site and came up with:

333882.....74-80...350/400......76cc chambers

now I know they are nothing special

that is the best flowing stock head for a 350

I always thought the 'camel hump' heads with 2.02/1.94 valves were the best stocker heads......64cc chamber for higher comp. too
