John, could you provide me with a part # for the diesel headgasket? I had seen references to it, but the bmw 4cyl diesel headgaskets I have seen appear to be shaped differently from those for the M42/M44 engines. Also, how much does that headgasket drop the compression on a stock motor?
As for the bit about the fasteners, I can get ARP hardware at decent prices, and I prefer a stud and nut to a SHCS for holding the head on. I have seen people use standard grade 12.9 fasteners as well... any particular reason you prefer cut down M3 bolts? I'd really rather not go cutting up and rethreading the ends of fasteners, it seems like you'd potentially trash the threads in the block or at the very least wreck the rolled threads and possibly heat treat at the end of the fasteners. |
