Yeah it's pretty bad. I have been having issues with the cooling systme. I blew one set of head gaskets already when I first got it running, I hope not another one, hopefully it's just the intake. The only reason I think it's the intake is because I'm not getting anything out of the exhaust like i did when I blew the head gaskets.I've never seen oil froth like that, in the absence of a lot of water (i.e. blown head gasket or if you're super-lucky a lower intake manifold gasket). You can get some aeration from overfilling but it doesn't look like that (modern detergent oils won't foam to that degree). That unfortunately looks like the typical milkshake from when that happens. Do you happen to also be missing quite a bit of coolant? And the oil level is higher than it should be? You'll definitely want to investigate before running again - bearing damage may already have happened. I hope I'm wrong.

Also if this thing needs to be rebuilt I'm considering doing a 351/408I've never seen oil froth like that, in the absence of a lot of water (i.e. blown head gasket or if you're super-lucky a lower intake manifold gasket).

All I have to relive crank case pressure is the breather on the passenger side fill.
As far as I know, ford added the pressure release hose on the oil filler neck in order to equalize the crankcase pressure in parallel with the PCV valve.
If it's in the back of the engine, then I'd bet that unequalized pressure is the culprit, since you DO have a breather vent, which might even have adequate flow, but the flow from the back of the crankcase to the front might not be sufficient for the pressure you're building, thus it escapes through the gasket.
