I was having a conversation with Jeff bush and he mentioned that he torque plates the block as well as the head. I can’t imagine that many of you have considered doing that to the head. For fun I decided to torque plate a head to check for distortion and I couldn’t believe how much the valves moved. Jeff also mentioned that Hes NEVER gone over 99 ft lbs with head studs and that over torquing will the distort the head . He said that’s the #1 mistake guys make. I’m really tempted to put a motor together and do a leakdown at 98 ft lbs and again at 110. I’ve always torqued the head to 110 with l19s. I probably get away with it because my motor is torqued plated At that spec. I wonder how many guys are creating head gasket issues on stock motors with arps. It is very possible that they are distorting the head.
