R53 Engine Questions

Does anybody know if the non-supercharged engine head will be a direct bolt on for a supercharged engine? I assume they would be compatible.

Thanks

NO the valves are different so you will burn the exh valves if you put an R50 head on R53. You can replace the valves with the S valves and it will work, but I'd also do guides and seals if it's used.
