yet another exhaust manifold query
welcome to the frustation of owning an Early Abody Mopar.
The engine bay is small.
You want easier, buy a 1967 and newer Abody or a Bbody.
Are you going to be street driving the car?
If your going to Drag race it in Superstock etc class,
then go for the headers.
Otherwise save your self a lot of headaches,
use the 273 manifolds.
A small newer style starter will help a lot,
I am using one, less weight, and spins the engine faster,
with less amperage draw. :) :)
Drivers side I suggest use a
copper exhaust gasket.
Lots of info on this site, use Search function.
Please, Look at, and read this thread, linked.

My 318 with cast # 302 heads had a minor exhaust leak with the 273 manifold, the copper exhaust gasket helped a ton.
Just a few suggestions, there is no easy way on the small Early Abody.
Take photos and share with us, of your car as you work on it. 8)
