N54 Head Gasket Recommendations

[inline6xi]

Going M11 all around and stock HG for now. I plan on taking apart the engine next season and not going crazy right now with the N52 head, just sorting the car out. Going to keep the HP on the low side sub 650whp but I do plan on upping the rev limit to 7600rpm with the head.

can you link some info on what is involved with the N52 head swap? I'm putting a new (used) engine into my 535...
