okay i got a question for all you buick guys, i have a 70' 350 and is it possible to put 76' 350 heads on a 70' block?
Yes you can, all buick heads are pretty much the same. The chamber cc's vary in different years but only by a couple cc's. All years used 1.875 intake valves. 68-74 heads used 1.5 exhast valves; 75-80 used 1.55. 69-51cc 70-49cc 71-50cc 72-50cc
