Scott, I looked all over and couldn't find the numbers. buickgod.com and taperformance.com had a lot of information on other engine specs, but not too much info on heads. http://www.buickgod.com/header.html?ID=3238 http://www.taperformance.com/facts.htm Thanks for the link it was just what I was looking for.

I know it only shows the 'Head Chamber Size in cc's' in the right hand column....but, at least it shows something for the 350's.
