<html><body>Has anyone ever stuck a magnet to a Payen <b>copper</b> gasket? I did-its a steel gasket with a copper coating. There is a real engineering issue with the 2660cc block and I am not sure why it is configured as it is. There may have been a study done on the engine's water flow way back then and some modifications made for cooling. It does not add up or make sense, however.<div><br></div><div>So, look at this head and the gasket and then the block. Why are the water passages reduced on the jackets shown? Then too, why is there no passage in one area marked that is actually open for water on the head<b> and</b> gasket? This is one "hot spot" found between 2-3 cylinders when read with a heat gun.</div><div><br></div><div>I was tempted to drill out the opening in the block before re-assembling my head, but thought better of it. I would never question engineering technology of BMC. Modern day replacements have that same area blocked. Never-the-less, can anyone explain this concept to me; the reason for this and a 4lb. radiator cap. This engine needs water, lots of it to keep it cool. Why restrict it? Then too, aluminum has its own set of issues that may/may not improve the cooling capacity of some old, thick cast iron block. Maybe throwing money at it has an effect.

Steven-that's a real heavy piston at .060 (compression ratio 9:1?)
Was there any defect in head prior to assembly? Magnafluxed? There
is an outfit Midwest Cylinder Head that can repair that for about
$500, or else is on to Denis Welch for about $4K.

<div>I just had my head off and checked-they shaved .003 to get it
flat. Fingers crossed-head gasket was not blown, but water in oil.
I'm hoping it was water intrusion from rocker studs. Hank</div>
