Reply:man, you do marvelous repairs!  although, every single one of your posts sounds like a recipe for grill chicken pre-heat oven to 350, bake for 45 minutes, turn over half way through, and post heat 350 for another 45 minutes.  cheers
Reply:What's the advantage of using A356 filler?  And why do you pre-heat your aluminum heads?  I've never pre-heated any of my cast aluminum parts and they seem to be holding fine.Common sense in an uncommon degree is what the world calls wisdom.
