Default How much of a increase with headers???

My ceramic Hooker longtube headers and Y pipe are being delivered tomorrow for my new 383 stroker. I was wonder what kind of increase in HP can I expect over the stock manifolds? Was it well worth the expense? Thanks!!! :cheers:

Trust me it's gonna be worth the expense. When I installed my headers I already had a cam but it was on stock heads and it's still a 350.

I gained 23 horsepower and 32 pounds of torque. Later when I installed my heads I got even more horsepower.

So, if you've got a stroker and you're still running on stock manifolds, you've got a LOT to gain. You're gonna be all smiles.
