340 heads on 360?

I'll just add this: A typical smog style 360 head (lets say 1977 360 heads) will perform very well. People buy X or J's thinking they've changed the world with their motor. If 2.02's are installed in the smog heads, and especially if mild bowl work is done even by a home porter, wow can these heads work.

• Let me add, 2.02's are not the tell-all either, as 1.88 is very serviceable in a milder street build.
