005 is also for crossdrilled block (like a 2.5 commonblock) and an older non-cross drilled head like a G-Head

When did this change??
P4452005 - non-cross-drilled head and block
P4452006 - cross-drilled head and block
Thanks

The 5281064/5281064AB is identical to the P4452005 gasket. The numbers were consolidated and the price went up.
The P4452006 is still around but now P4452006AB.
The gasket I preferred to use was the 5281065, it was identical to the '006' (no large water holes, just cross drill)but only had the single rear cross drilled holes. Of the handful of engines I worked on that were factory original builds that was always the gasket present and it matched the head and block configuration without any extra holes to worry about leaking. It was discontinued awhile back unfortunately though:(
I have used 1064/ 005 gaskets on crossdrilled and non-crossdrilled engines. O ringed blocks too.
I concur with what others are saying. I always use the 2005/1064 gasket for crossdrilled and non-crossdrilled and mismatched applications with good results. That is when I don't use a Cometic MLS gasket. Zero heating/cooling issues.
