I ran a manifold for about 3 years without a heat riser. My original ('72 manifold) was cracked and the manifold that came with my current engine (a '73) was frozen solid from sitting out in the elements. So I removed the flap valve and shaft, and installed a nut and bold on each side. Never a drivability problemin cold or hot weather, mainly because I still used (and continue to use) the stock air cleaner with the heat stove around the manifold outlet.
If you REMOVED the flapper, then what you are left with is FULL ON manifold heat. IOW, of course you'd never have cold driveability problems!

Or are you saying that you bolted the flapper in the "no heat" position?

Not, with the flapper removed there is limited to no manifold heat from the exhaust manifold. The only heat that is transfered is from the metal to metal contact of the exhaust/intake manifolds.
