Hey Crin

The specialty machine shop that rebuilt my motor sent me away with instructions to torque the head nuts to 63 FOOT POUNDS. I think I have been doing 65. They even said one torque after the first heat cycle would suffice and it wasn't until a knowledgeable member on here advised me to do it 3 times before installing the motor, a couple of weeks apart, then after 1 heat cycle, then 50 miles then 200 miles. Now Dave is saying 'until they no longer move' and that sounds like very good advice as well. Re you mentioning acorn nuts/washers, those heads would have normally (I believe) come with standard open end nuts, so bottoming out would not be an issue. In wanting to dress my six up a bit I opted for polished stainless acorn nuts. They cam with quite-thick washers (also polished stainless) which definitely lift the nuts up off the head a bit and allow some torque room. Any way you could remove an inner nut and measure what you have for clearance and then bottom a nut out on a bolt in a vise and compare clearances?? Also, very recently, someone posted Packard's torque-pattern sequence for the sixes and the eights - t'would be a good guide to follow, yes/no?? Chris
