I had no idea that sharing my stupid take on this hobby would end up here but oh well here is my tourqe wrench. It was probably $15 at harbor freight and it is a 3/8" drive little thing. I used this wrench only to snuggle down the rod bolts and main cap bolts before angling them so I did us for that, but I still trust my own hand more to get something tight enough, I just use a breaker bar on new head bolts and just kinda visualize where my angle should stop
