My engine is not long studded, and neither is Karl's.

I had a 6 long stud engine, and a 10 long stud engine, and both suffered head gasket failure, and when the studs were measured, they were all different lengths.

I have had no trouble whatsoever with standard head bolts.
I understand the physics behind Karl's logic here, and will never have another block long studded.

Like Karl said, don't do it.
