I was told you can use carrera heads in the 930 engine for my efi conversion using carrera intake manifold? How hard are they install if possible? thanks

 

The 3.2 Carrera heads are a direct bolt on to the 930 and are commonly used. From my flow testing, the ports flow very well in stock form and only need some minor clean up. Be aware that the 3.2 Carrera heads are not made from the same material as the 930 head so they do not resist heat as well. In practical terms, I've not seen this to be a big deal using 1bar or less, however, I've not seen a large number of engines with the 3.2 Carrera heads since I'd rather port the 930 heads to size.

 

ok, that makes sense. I think I will just port the 930 heads. thanks geoff
