That's good to know. Looks like I'll be using headers. Thanks Bear I appreciate your help
Good luck! Obviously I don't know my 65's as well as I do 69's
--- Maybe GeeTee knows which headers are the least painful on 65's --- they all suck, just some suck less.
I too have round port Edelbrocks on my 69 and am running Doug's D567's on it. To get them to work, I had to make some changes:
Relocate the brake distribution block from the inside of the drivers side frame rail to the top.
- Convert to a mini-starter, otherwise R&R of the starter on the drivers side would not be possible without loosening the header.
- Re-bend and re-route the rod that operates the 'back drive' linkage between the transmission and the steering column lock.
- Re-route the transmission cooler lines away from the passenger side header to keep them from getting heated
After that, still if/when I remove the passenger side lower control arm I'm going to have to move the header out of the way in order to remove one of the bolts. If I were to turn the bolt around backwards so that the nut end is next to the header, the end of the bolt that sticks out through the nut would wear a hole in that tube - that's how close it is.
I like RemFlex graphite gaskets
'This time' I replaced some of the bolts on both sides with studs. This makes it a LOT easier if you ever have to loosen and reinstall the headers because you can "hang" the gasket and the header on the studs and not have to try to hold them both in place while you start the bolts.
If you want protective coating, the way to go is to buy bare headers and then send them off to JetHot for coating. Their coating is better - especially if you get the upgraded "extreme heat" coating. I had mine done in a dark blue that goes really well with the 69 silver blue metallic engine paint.
I have no direct experience with other brands, but I have "heard" that MadDog headers fit well.
