I have them installed on a '70 K20 with vortec heads. I know, the 2wd's vs. the 4x4s are different because of motor mount locations. The 2wd's are more difficult to run because of the IFS cross member. With that said, the pass side fits well, lots of clearance. The driver's side is so close to the cross member I will need to notch it for clearance. I bought cheap dorman manifolds & trimmed off the brackets. Hard to see but the forward exhaust stud is 1/4" away from the cross member.
