I was under the impression that D3VE A2A heads had a 91cc combustion chamber.
What do I have?

I too Have the same heads, D3VE A2A heads. I think they are 91cc chambers but not 100% sure.

Where did you get that info? I had mine cc'd after the combustion chambers were polished and they came out to 99cc's. Polishing the chambers will only change them 2-3 cc's. I was pretty sure they were 96cc's to begin with. Thanks.

 

Checkout www.385-series.com
They seem to have accurate info on all 429-460's in detail.
