supra head gasket questions+ rebuild

[Andy C]

thanks about the oil cap, ill get straight on it.

well couldn't gete under the car so got them out from the top and a couple of others thinking these were the ones i was touching, ill be able to see more once the turbo is out.

went to disconnect the turbo from the exhaust and once i took the nuts off i noticed the thread has to come off looks like a female torx socket..
does anyone else have these?? seems a little odd, i think i have disconnected everything still seems pretty tight though.

I'm quite nervous about it all as Ive never attempted this sort of thing before, I'm taking it slow. not to sure what to do with the head just skim it or the more, really depends on money any way more later with some pics
