Re: head bolt torque

25 ain't enough. Been a "hot" topic before. Best i've seen and use is three graduations up to 38/40 lbs final. Book and some use tha extra 90 degrees but i've seen too many block threads go south with this 90 degree stuff. But we remove heads ta check things a lot. I know tha 38 lbs will hold any stock motor out there cause some of our motors are well north of 200/230+ lbs.................JMO

BTW, think tha pattern is numbered on tha heads maybe..........
