Tidbit:
Don't use allen head bolts on the down pipe to turbo connection. I wanted to use them because they are stronger than grade 8 and heat treated for high temp use but they are impossible to get tight in that location. So now I am off to NAPA at lunch to high temp treat hex bolts. I did get the turbo bolted up and the lines ran though so the hard part is done.

When I took my engine to the engine shop the old guy at the shop told me to never use hardware store junk bolts (as he called them). So I actually did a bit of research as to what the numbers meant on the bolt heads and the differences between metric bolts and SAE bolts and I found the steel bolts I bought from Lowes were really low grade and not heat treated. The same goes for the bolts that Autozone, Oreilly's and Advance carry.
The guy at Advance told me only NAPA or fastenal would carry bolts like that. I did get some nuts from Fastenal and Advance special ordered the studs I needed but neither had what I wanted otherwise so I went to NAPA and got the allen head shoulder bolts I wanted because they are heat treated and Grade 12.9. They had the best assortment of high strength heat treated bolts so that is my go to place. They also have 10.9 (grade 8) hex bolts that are heat treated so I will go with those I guess since it is too tight of a fit to go with shoulder bolts.

Wait a minute....
, yeah I figured getting quality bolts, fittings, and hoses was probably a smart idea. Hopefully it is money well spent.

Yeah I have studs and 10.9 nuts for them left, I had to buy a bag of 25 of the nuts from fastenal. To use the studs I have will have to be cut if used on the bottom holes of the Greddy manifold as they are too long.

The allen head shoulder bolts worked fine on the air pump port (using my RB block off plate) on the downpipe and the oil drain fitting so since I have them, You should use them at those areas. I also used allen head shoulder bolts and lock washers on the inlet pipe and outlet pipe of the turbine. The inlet requires two bolts of the same size but the turbine outlet pipe requires one shirt bolt and one long bolt. Shoulder bolts hold the inter-cooler to the brackets as well.
I'm gonna cross post this in my thread.

I highly recommend studs on the manifold to turbo connection but only three, the fourth hole at the rear is a bitch to get too so I used a grade 8 heat treated hex bolt there with a lock washer since it was easy to get too using a rachet end wrench. using a stud and a nut there could be a pain but still doable.

I have a set of allen head sockets so as long as they are fairly easy to get too they are good because they are grade 12.9 and very hard to break or to stretch from heat. 1500F-1800F is a lot of heat. But in tight spots they are a pain in the ***.
