I thought all the Ford modular V8 engines were interference engines but I could be wrong.

Yeah. Even 1 tooth off on the timing chain and you have contact. It's actually quite tight

12.5:1 domed pistons don't leave much room for clearance I suppose.

"In comparison to non-interference engines, interference engines “breathe” better because the valves can open earlier, close later and open wider. Interference engines can also achieve higher compression ratios. These designs extract more power, use less fuel and generate fewer emissions."
