Questions: I've read that some of these heads had a problem with leaking anti freeze. If so has this problem been resolved
Question By: Don Gray on Sep 19 2018 11:56 PM
No, what you typically see is where people dont use sealant on the studs. This needs to be done when installing a flat head.

Questions: How can I tell if the head is warped? I had an issue with the thermostat and the engine got pretty hot.

I would take it to a machine shop to have them deck it and check.
