Thanks, good to know I'm on the right track. Quick online search brought exhaust manifold temperatures around 900F (at exhaust port). Which makes sense since Aluminium Melting point is 1218F so it can not be any more higher than 1000F. I'm thinking the temperatures at the hose connector location are much, much lower. And I will be using cup pipe as well.

Any issues getting the tstat to oil filter housing line to fit ?
I ordered the bits from Elephant on Friday to go the same route. No problem with any of the other hoses for me, but that one has been a challenge from other sources. I tried the Porsche part (easily kinks), an OEM version (also kinked, though not as badly), and had a line made with Gates Green Stripe (too large a diameter to fit beside the oil tank). It's been a crusade....

I think it all depends if your oil tank is out. I don't know if it's even possible to snake the line in past the oil tank if its in place. I attempted it twice. The first time I couldn't position the oil tank in place when the elephamt line was tightly secured on the tstat and I couldn't fit the short L shaped rubber hose from tank to tstat.
Second time mounted the small L hose on the tank before fitting it in the place. Then I loosened the nut on the elephant tstat oil filter line to allow some play. I fitted the funny shaped short hose on the body end of the oil fill line. Put erything in it proper location and tightened the big tstat nut and clamped all the lines. It wasn't easy but definitely with time and some maneuvering it will go back in place how it suppostu.
Good thing would be to mark the angles of the original fittings exactly like on original lines or test your lines before taking them for crimping and mark the angles using white sharpie.

Today was pretty big day for me. It was a crank assembly day!
I was very careful and worked in clean environment. No photos from the assembly as I paid 100% attention to the work I was doing. After researching the Glyco bearings, reading comments about fitment issues and listening to forum members here I decided to order all bearings through Porsche Dealership. Each bearing had 6 measurement marks as well as control sticker on the box. No issues fitting them in. All rods spin freely after tightening procedure. Although after doing the work today I wish I had 3 hands
I am getting ready for case assembly now.
Any advice?
Thanks!

Seeing that last pic is like catnip... Makes the mind race... Subscribed... Regarding your work with the oil lines, can you imagine what the engineering sessions were like designing the plumbing on these cars.... Would liked to have been a fly on the wall.

Are those red thru-bolt o-ring? You should use the green Viton O-rings.

Yes, they came in in a bottom end kit. Any reason why not to use them? Was there a Porsche bulletin about those?
Quick research points to both red and green being the same and only the blue are bad. Can someone confirm?
Thanks!

Updates:
1- New 993 turbo head studs installed (no pictures) chased the threads first, then set height. I was baffled at first that the studs would just barely bottom out at the proper height and still feel like they should be driven further, but then the thread locker set and they felt exactly like head studs should
2- New rings
3- And now for the bitter part - I have run in to a problem.
I needed to replace 2 rocker arms and instead of polishing the old ones I bought brand new from Porsche PN: 930-105-043-00 (superseded to xxx-02 and later to xxx-05)
To start with they look different, the old ones are nicely polished on the sides and the contact area appears to be bigger. New rocker arms are rough to touch and look like they are unfinished. The marking on the shaft are also different. But, the most baffling is: the rocker shaft (boss) does not fit in the new rocker arm at all.
What's going on?
Thanks!
