NC hybrid setup/coolant blows heater core/how to avoid?

[Ross Corrigan]

I know this is NC but I"ve exhausted my related Nissan/Datsun list w/ no
good info.

A few of us have sb chevy V8's and several have experienced heater core
problems d/2 higher/greater coolant flows/pressure (I don't know
specifically), they've replaced w/ brand new units and halfway thru winding
out and leaving another NSX (their ride, mine wouldn't do that;^) their
heater core will fail again.

They only discussed ways to just bypass the heater core which is simple but
I live in the often rainy pacific nw so need heat occassionally throughout
the year and would prefer some sort of pressure reducer mini-manifold but
I"m not familiar w/ what hardwar is out their or the simplest way to solve
this.  I'm not sure if it's simply a matter of too much flow or pressure or
combo of both that fails them.  Mine's still OK but I haven't ran it very
hard yet and want to preempt a painful heater core R&R etc.

thanks for any and all ideas in advance
