looking at some parts that may be for sale soon.. have casting numbers from heads. 2406518. that is orig mw casting number i think but this set of heads were purchased when mp recast them and after all bugs were worked out. i think 1st castings leaked water from everywhere. 4532287 is the other number. supposedly are stage v heads. where can i get a list of the casting numbers? i looked at some old mp catalogs but nothing seems to come up by casting numbers. are heads worth using if they can be purchased reasonably/ thanks in advance.
