Ok im looking at the add they have in a magazine about their new lt1 head. And they basicly are saying its built for Forced induction or nitrious setups. So are they saying its not going to help you N/A?

I figured better flow, is better flow, wtf?

Would their be any problems if I decided to run those heads with lets say a cc306 cam, or comparible cam?

 

They say they're for forced induction since the combustion chambers are bigger, so compression gets dropped. With some work you could make them for na use though.

Edelbrock also has some heads that are designed for na use, I don't know about flow #s, but I think they've got bigger valves.

Of course, if your want some really good heads, I would go with Air Flow Research heads...

 

This is one where you really need to try a "search".... there is an extensive thread on these heads, including input direct from a representative of Trick Flow.
