'69 big block headers

I have a 69 Mach 1 with no engine (original 351W M code) and FMX trans. I have a rebuildable '66 428 from a Galaxie and plan to install it and its C6 trans.  The heads are C6AE-R which are roughly equivalent to CJs after exhaust porting and larger valves.  I would like to use long tube headers, but am unsure as to where the actual exhaust port opening will mate to tube opening of the header  because the vertical position of the port varies from one FE head to another-even though the vertical bolt hole positions are constant. Obviously the port and tube opening have to match for any realistic performance.  Which head was modeled for the header construct? Does anyone have experience here? Hooker vs Hedman? other brands I don't know of? Using these original heads saves me a bunch of money and will produce all the power I need, so I'd rather not buy other heads. thanks

You may want to check out headman headers web site and see what they have, as they have some special built headers for the mustangs including headers to fit 351 windsors in the 64-66 mustangs without having to bash the towers out of the way.

I'd give the people at Ford Powertrain Applications a shout. FPA has several header designs for all the various head options and big-block Ford stuff is one of their specialties...

Don't use Hooker 6901-1. The driver's side won't fit and Hooker will tell you it's the motor mounts or some other reason other than accepting responsibility for their poor design and/or worn out dies they use to make the pipes.
