70 ft lbs... Check the BOLTS first for stretch before putting them back in. Bolt sets aren't cheap, but the last thing you want is a broken head bolt

Re: lb8 head stud torque specs
i reused the head bolt son my turbo motor but i dont recomend it, buy new ones and be done with it. dont forget to chase the threaded bolt holes in the block before installing the new bolts and do not put oil on the head bolt threads
