360 Head Options

Thanks for the replies, keep them coming.
I thought the eddies would have to be heavily ported to make around 600hp.

After a bit more searching I have found the Airwolf heads are a Pocomp casting, the quality of Procomp gear in OZ is very lame. Are the Procomp heads any good in the US?

What about the W5 heads?

This is what I have just bought.
Looks good but does not have the power to match.
