The upper radiator hose barely has any coolant flow through it; my survivor 69 Charger with completely untouched original 383 has MUCH more pressure/flow in the upper radiator hose.
We're definitely on to something there. I've wondered about the slit head gaskets too but iirc people have said they are OK for the most part. But we certainly have a restricted flow for some reason that has to be what is causing this. can you post a larger pic that shows all the holes from front to rear? (to try & get an idea if the total/overall restriction is somewhere other than the gaskets). I have a good cooling mod read for you on circle track chat, a subset from moparchat (VERY informative) that relates directly to this but one thing at a time.
No the slits are not why, there are thousands of big blocks out there running head gaskets like that.
Well it's good to see you John (its been awhile) & we've missed you! (ahem). what I was saying which you can see if you reread it is that the minimal flow is an obvious clue. John I am disheartened to see that you have not let this go after all these years.
I read it fine, you are claiming his diminished flow is because of the slits in the gasket is how it reads.
There is minimal flow thru those slits , his dimished flow has little to do with the size of those slits, someone a lot smarter than you, or I, redesigned that head gasket. Why ???
