Q-jet Questions

Yeah, thanks Danny !

I reckin it's sorta like the heads. If you must used unported heads, then obviously, some of 'em will flow more than others, or produce quicker ET's for whatever reason.

That brings up another question. Do most of the quick Stocker guys gather large numbers of heads and do flow bench testing on 'em to find the best ones for their engine ?

I realize that heads for some of the older cars are getting harder to find. But I'll just use the Pontiac 6x heads for an example. These heads are quite common and cheap. So somebody with the $ to spend could by up large numbers of these heads, and identify the best ones on a flow bench. So is this type of thing a common practice among Stock racers ?
