Default Re: Copper head gasket or best Kevlar?

Could also do radiator exhaust test yourself. $45 dollar Napa Block test kit.

Radiator issue? -How old is it?
- Has it been flushed and back flushed recently?
- Empty it, block the upper and lower openings, should hold 1 1/2 gallons.
- Could be partially plugged or if old fins not making good contact with tubes.
- How old is the radiator, fins/inch, rows ?.
- When run and and stop/turn off, does it burp coolant? (running hot?)
