I am using a VDO cylinder head temp gauge with a VDO sender under the #3
spark plug.  I am also using quad tip platinum plugs.  I was using 3
electrode copper plugs but the temps went to 350 degrees.

I have a customized 2L T4 engine.  I am running a set of zero-deck square
port heads (same head used in Vanagons, they are from a 79 bus though).  The
engine was designed to eliminate the troublesome head gasket.  I also am
using a modified 914 Porsche Bursh racing exhaust.  I have dual dual-throat
Dellorto 40mm carbs with the update kit (Temps went down with the kit).  And
a full race balance.

In the spring when the fuel formula changes, the temps go down...

This is my other "Customized" VW
