I use the Summit true roller chain and gear set. Yup TDC drop it in on the 4 degree advance notch. Car runs super. Now if this were a big dollar Hemi roller motor or a motor for an all out race car i'd go the degree wheel root. For a street car dot to dot is fine. Repair shops have been replacing timing chains for 50 years just doing dot to dot. Yes it may in reality be 1 degree either way but runs fine.
