yeah i recently replaced my bottom end when i torqued the head bolts down it was quite difficult because they would not all go down properly. i torqued to i believe 58lbs but i heard i needed to reloosen the bolts then retorque down to 14lbs ? this sounded fishy is this true and why . because im starting to show knock and i was wondering could this be causeing the problem. its a random knock every once in a while on my safc2. help i really and dead stuck on this problem i use to run at 18psi now i cant even go that high without show a level 100+ knock..
