FA20 Interference...

Definitely. The valves can hit each other or the piston. It also uses a timing chain so you would have to put something together wrong for it to happen. Maybe you could get the valves to hit with avcs but I kind of doubt it with stock parts.

Thanks. Now the answer is easily search-able.
