Rb25 Neo Turbo, Couple Of Quick Questions

[Gcjosh]

Yes I've searched, and Ive found conflicting answers hence why I'm asking here.

1. Do you need to remove camshafts to remove the head? I've read yes and no, I don't see why you would have to take them out.

2. I'm chasing around the 550-600 hp range, is it worthwhile changing valve springs while the head is off?

3. What thickness head gasket? I've read stick with 1.1mm but pros and cons of going thicker?

Preferably I'd like to know of a good shop on the Gold Coast I can talk with if anyone has some recommendations??

Thanks

Josh

1.no

2.not really

3. Stay stock

Leave head on, change to arp studs. Boost it.

I would leave it on but the pcv valve was blocked off and there is sludge all over the cams , so I'd rather take it off, get it cleaned properly and can check for cracked/damaged Pistons etc

If you are going to do what is written in your last post, then why would you object to removing the cams from the head before removing the head anyway? On that basis, if there was lots of sludge up top, I would disassemble the top of the head in car, carefully remove sludge with the head still installed and then go back to driving around an unopened motor. They're never as good once the head has been lifted (is the general consensus around here).
