[QUOTE=hllywdb;11669709]CP I wish they made a Galbreath head for the 020 I use them on all my TDs and AMEs that are modified to scream. I added shims after burning out 2 in 20 sec. The first one came with the motor so I thought it could have been softt.
Cheer up hllwdb-they do...or rather Doug Galbreath will convert your old burnt out head to take a Nelson insert.....note an insert, not a plug-but still works. One of the other engine guys-Bob Mattes? or Bob Beecroft? also offers the same service......quite a bit of work involved though-and as I recall they prefer you send the whole engine, as they have to get the clearances right for the conversion to work properly....
