---back in the early 1980's when I was seriously doing aluminum heads I was chatting with JV Brotherton---the BRO of Brodix---and I asked him his opinion just on simple shelf life of new heads ---He told me the very best day of a new properly heat treated head is the next day after it had cooled off...

Brazing a cast iron crack -I do NOT care for cast iron welding of the block, but instead I would braze the crack. -That needs to be done by somebody who KNOWS what they are doing. -------------------------------------------- -When blocks are cast iron welded they heat the block so bad that the block...
