It's amazing how these so called 'performance' shops can be such hacks sometimes. I would take that block back to where you got it done, and tell him to get busy. Why should you be throwing your good money away? Im not a fan of ever having the pistons above the deck, for any reason. Thats just asking for trouble. (As you see!) Man, Im sorry to hear of this problem. Nothing much short of a re-do will fix this one. I personally wouldnt worry about the oil seeping out of the pushrods, as long as you're getting oil up there, you dont need it to be spraying out. Im also not a fan of oil restrictors, I think they cause more problems that they help. But that's just my opinion. John
