And that is exactly why I am on here asking questions NOW rather than second-guessing myself after the fact. You can't put metal back, as the saying goes. Also, I'm not trying to second guess my machinist, any more than someone undergoing cancer treatment is "second guessing" their doctor or hospital by gathering a second opinion. If I was building a SB Chevy he could probably recite the head flow numbers in his sleep, but from what I see going through his shop, LA Mopar is not a huge part of his business. You can't fault someone for that, but I'm not one to take someone else's word on something without doing a little homework. It's called "due diligence".
