For head porting I would recommend Speedworks in Ringwood and for engine dyno I would use Gene Cook in Tullamarine good operator just had my engine dynoed there.

I ported my Hold6 alloy head around 15 years ago and even now after doing a few more heads would not alter what I did back then.
The basic port casting is fine, you just need to smoothen it all out, narrow down the valve boss, leave the short side radius pretty much as it is except smoothen it out.
I used a Vk fuel injection manifold and took alot out of one side of the runners to match the cross section of the head entrance. This is where the biggest
restriction is if using a VK injection manifold.

Cost of dyno from memory was between $600 to $800, it works out about $110 an hour.
