hey, so im about to change my BTR springs (due to clocking about 25k on them) and was wondering if anyone knows a good method to change the springs and tighten down the rockers with out pulling the timing chain cover. i know i can get the springs by doing the TDC method with a straw but not sure about using this method to torque my rockers. any ideas? i dont wana pull the timing chain cover cause i have pinned the crank and dont wana deal with that.
