Anybody out there with Offy heads that does NOT have cooling problems at idle?
The brand of heads has nothing to do with heating problems.
A properly built and installed flathead will not overheat
at idle or anywhere else in the operating range of the engine.
Almost all heating problems are caused by the engine builder neglecting to perform the first and most important step in the rebuild. That is, acid strip the block.
Stripping should be done BEFORE magnafluxing and pressure testing.
