CHI will be releasing a non high port 2V for clevo owners who don't wish to run high port heads. They shall hit the shelves within the next few months They're better than the cast iron counter part but not as good powerwise as their high ported counter parts.
I was told this on Monday but forgot all about it. We'll have to wait and see till the end user gets their hands on them to find out what they are capable of
I wonder what would go better in an under bonnet application. A high port head with a milled manifold plenum, or a non high port head with the manifold plenum untouched.
Does the non high port apply to the exhaust as well?
I'd guess not given the amount of machining involved.... I mean, Iron CHIs cost the same as alloy chis don't they?

I think you will find the iron version is more expensive due to the low production numbers.Cost will be a factor as soon enough the likes of CHI and AFD will be competing with Edelbrock.
My CHI's had only 60cc's when fitted with my valves So 58cc wouldn't be asking too much. Mine are probably going to get a skim. So they'll probably come back 58-59cc.
