Sanderson or Hedman Hedders?

I am in the process of putting in a 305 into my S10. I have the engine assembled and changed my mind on using stock manifold.

Now I am trying to decide on headers that wont set me back too much more money than I already have into this....

Sanderson Headers
3/8" thick gasketless flange, 1-1/2" primary tubes, 2-1/2" collectors
$199.00

3/8" thick gasketless flange, 1-5/8" primary tubes, 2-1/2" collectors
$229.00


Hedman Hedders
1/4" thick flange, 1 1/2 in. primary tubes, 2 1/2 in. collectors
$119.95

I guess the real difference here is the flange. Will 1/8" be that much of a difference? What is your experience with either of these companies?

I have a set of Sandersons for my street rod that I have not installed yet. I am not very impressed with the ceramic coating on them, it appears uneven and splotchy. the Sandersons are going to run you more than the Hedman I think. I would go with the Hedman 's.

The 1-1/2" tubes will give you more low end. The 1.5/8" tubes will perform better at higher RPM with all conditions being equal. Have you looked at Hooker also?

Bigger tubes on your headers can hurt performance, especially on lower cube motors. Smaller tubes will help your bottom end torque. If you go too large, you will lose bottom end. Something to think about. Bigger is not always better.

I hear that a 1/4" flange leaks all the time. Is this true? Any tricks on how to get around these leaks?

Don't even bother buying headers if you get 1 1/2" primaries. You are better off with stock exhausts with that diameter. Headers have to be retorked all the time, rust, and are louder. If you still think you need headers then get some 1 5/8" Hedmans.

Also, if you get headers I would recommend buying some Percy's header gaskets. I have been using them since they came out and have never had a leak. I have even reused them multiple times. Once they set initially, I have noticed that they don't need to be retorqued as often.

305s have decent torque. 1 5/8" primary tubes won't lose any of that torque down low. 1 1/2" tubes are a waste of money on anything above 300 cubes.

Get the Hookers. That would be your smartest choice. It would be worth it to get the coated ones.
