Head gaskets should not be any problem as the manual calls for compression to run between 130 and 165 pounds (from the cylinder outward).

Just an idea. Can you bypass the radiator with a piece of hose of some description?
Also if you are worried about the pressure, try hooking up a compressor with the pressure regulated to less than 20 psi.

Here's a question for Dave, but others may have some insight as well.
My '67, 440 cid (Imperial engine) has newly
replaced freeze plugs, and a lot of casting
sand and junk in the cooling system. Prior to
doing a closed system flushing with "Cascade",
I want to get most of the garbage out using a
garden hose on the lower radiator hose, thereby
avoiding the redone radiator.
We all know 15-18 psi is what a radiator cap
opens at. However, my garden hose may be as
high as 25 to 30+ psi. Can the head gaskets,
etc. and inside of the engine take that kind of
pressure? Does anyone know what pressure
exists inside the block? O r would I be wiser
(with this old , tired engine) to just throw an
old radiator on and do a closed system flush?
Any other drawbacks to my open system flush?
Thanks for any input.
