hedman swap headers

[Blackpony]

Anyone use the hedman 45660 swap headers? I just ordered a set today, hoping they fit and work pretty well. Once I know they work good and such I plan to have my local powdercoater ceramic coat them. He is much cheaper then the difference they want to buy them already coated, so saves a little money too..

I was looking at these too. Keep us updated when they come in.

[Blackpony]

will do, hopefully they get here before the weekend, if so then I plan to get them installed and get to the muffler shop to have the exhaust hooked back up.

[p3ug]

Did you have a chance to get these in ?

[Blackpony]

Yes I did. They fit fantastic! Tons of room all around, they slipped right in. Here are a few dark photos I'll try and grab a few better ones tomorrow.

They look good. Do they hang below the frame at all? I think these are what I'm going to go with also.

[68GMCCustom]

look like a good alternative to the DT's.

[Blackpony]

No they are above the frame. It's kind of a tight bend after the collector to keep it that way but the muffler shop did a great job keeping it tucked. Anyone looking for swap headers I highly suggest these!

What engine mounts are you using?

[crazy longhorn]

Very nice fit on that "square body" For the 67-72 crowd, my bet is that they will not fit with stock mounts/stands....swap to the 73-up mounts/stands, & I will bet that you are good to go? Longhorn

I bought some adapter plates off eBay, then used the factory mounts from there. Just redrilled the frame for the trans crossmember and the factory shifter linkages all hooked right up.

They look good, and I'm wondering how the fit flipped (turbo style).

[bdydrppup]

do you think they would clear with a 2.5" z? so raising the motor 2.5".I tried the schoenfeld long tubes and they hit my control arm on the driver side and floor board on the passenger side.

[Blackpony]

I doubt they will fit with a z. I'll try and get a few pics tomorrow if isn't raining.

What size primary tubes are they

[Blackpony]

They are 1 3/4 primary 3'' ball and socket collectors.

I wonder how these would fit in the 60-66 rigs

[jamesjones]

The long tube 67+ headers look like they might fit my setup...hmmm...

Resurrecting this thread. Anybody tried the long tubes? Thinking about running the 1 7/8".

I'm running them on mine. Square body though. Only issue, I had to slightly clearance the frame on the drivers side. One primary tube was touching the frame, with a minutes work of the grinder, it was taken care of.
