The metallurgy has been improved to eliminate the cracking issues that plagued these heads from the factory; No more cracks!  The iron used in the new heads utilizes molybdenum, a metal yielding a 20-25% increase in strength, without being brittle. Additionally, changes of the water jacket design in the heads have helped address the 6.5's overheating problems. The original 6.5 & 6.2 cylinder heads produced by GM were prone to developing small cracks between the valves. The new redesigned heads have added chromium to the cast-iron to virtually eliminate these and other cracking issues.
All alignments and bolt-holes are exact fit for all factory components on your old engine to bolt right up.
You
will need new head gaskets and new OEM style head bolt sets (they
are one time use only, stretch-to-yield type).
