From the numbers that you give I come up with a new time of 10.11 ET. But I was off .06 on guessing Brain's numbers so its just in the ball park.

I was told by a performance company that putting these new heads on compared to the old ones and the carb is getting dynoed(flow tested) by him and also setting the ladder bar down to the bottom hole from the middle i would gain around 4/10 th do u guys agree......thanks

I would say that a 4/10th statement could be true because a fine tuned package can make all the diffance in the world. If the chassis is not right then you can pick up some time there if the carb is not right you can pick up time there an you can always pick up time with a better flowing head for a complete combo. So is it possible to get 4/10th from a fine tuned package I would say so.

Why is he recommending you drop the ladder bars one hole?

If the car hooks like it appears to be in your avatar why would you mess with the suspension? :?

well i will tell you what i have been told by some very knowledgable men...my intake team "g" IS NOT WORTH A CUSS...i have a great set of heads (ported brodix)..but they are not doing me 100% what they are designed to do with my current intake..
same with you..i am not famailer with a hurricane intake..but i can tell you from a common sense stand point..if your intake is not up to snuff. your heads will not stand as tall as they should.

I'll just say flow #'s arent everything,
I've used the hurricane intake before and had good luck with it, I think you'll see some gain .10 I wouldnt change the ladder bar holes though, looks to be working well already.
