heads:
6272292....70-78...oval...OPEN...402, 454

block:
3999289....454.......72-79...2 or 4 bolt, some "CE" replacement blocks had four bolt main caps

easiest way i know to find out about the weiand intake, is go to

and find the weiand section and look up the numbers.

last three numbers in the long number i decoded it with, you have 292 heads. my heads are:

3973487....71-72...350..........used on 71-72 350 LT1, 75cc chamber
