About 300-325. The heads are seriously holding you back.
The intake and cam are also mismatched.
What headers? What is the exhaust behind the headers?

Re: Feel like guessing HP?
After looking up the heads I figured they were junk and crack prone.
Not sure on the headers and exhaust,but I do plan on replacing it with Heddman shorty headers and Y pipe.
Can you explain why the intake and cam are mismatched so In the future I know how to choose the right parts?
IYO,how much should I gain with a good set of heads?

Re: Feel like guessing HP?
So would a 1,500-6,500 intake match with the cam or a Idle-6,000 intake be a better choice?
Would there be a noticeable power difference to justify spending the money?

An Edelbrock Performer RPM would work well with that cam.
That Idle-6000 intake is basically the same thing you have now. Their "Stage 2" intake is basically a copy of the RPM. The "Stage 3" is a copy of the Air Gap RPM.

Five7kid, how much would you say I should gain with a good set of heads and would there be a noticeable power difference in swapping intakes to justify spending the money?
