Back again to pick some brains!

Here's what I'm dealing with. I'm putting a 68 390 in my 63 Country Sedan wagon.

Car has power steering and still has column shifted three speed.

I have mismatched set of factory long tube headers. Left side is early style (C3casting) and right side is later style (c5 casting).

Wanting to know if I can use the set as is or can I expect fitment issues.

Oh, the heads are standard C8AE-H.

Thanks, in advance for any advice or information.

You will have a clearance issue with the Z bar on the driver's side as 427's used a different Z bar than 352-406's. You can modify the Z bar you have to clear. Don't think the C5 passenger's side will fit as Ford changed the frames in 65. I used shorties on my wagon and didn't have a problem.

I don't know if it is true or not, but I was told that the long tube cast iron headers won't work on cars with power steering. The shorty cast iron headers will clear all the power steering parts.

some of those heads have diffrent bolt patterns at exhaust ports....
make sure they match up...

Just wanted to say thanks to those that have replied so far.

I've seen posts here where the long tubes fit power steering cars so I think I okay there.

Also my heads have the vertical bolt pattern so the fit to the heads should be okay.

My concerns are:

1. Fitting with column shift 3 speed
2. Late RH header fitting to 63 frame.

Again, thanks to all.

Don't think you'll have a problem with with the 3-speed linkage, just the Z bar for the clutch. I tried C5 headers on my 63 406 way back in 67 and they would not fit.
