Yes, but I have the older, 'square' sohc head. The newer 'round' sohc head doesn't seem to have this problem; the header relief in the 'round' head is deeper and allows the exhaust to sit deeper in the engine. I believe the newer 'round' head also reverses the direction of the header collars as well.
Bottom line:
Older, square SOHC head means you might need to replace the studs. I could get the nuts on the studs, but just barely. I wasn't comfortable with it. There does seem to be some variation in the depth that these studs are inserted, so your mileage may vary.
