Hi, and welcome to the V8Buick board!

We're pretty friendly around here and a first name with your posts would be greatly appreciated by everyone :TU:

Check out the NHRA website for the head specs for each year.

Here (http://www.nhra.com/tech_specs/engine/index.html#buick) is the website.

Enjoy!
