why are these 2 things different on engine i ordered

[stud3737]

I have a 99 engine that I have taken out (got stolen guy blew up my engine...) and I have ordered a used one thats suppose to be a 99 but theres a few differences and I am wondering why these things are different. The 1st and 2nd photo are of the coolant lines to the turbo. It was the stock turbo on there. The 1st one is on the block that was previously in my car. Now should I move that to the other engine or just leave the one that is on there. The 3rd and 4th is what confuses me the most...why is the 3rd pic (one previously in car) an end like that (12 point?) vs in the 4th pic it has a 6 point. Does that mean the engines aren't the same year? Both blocks are suppose to be stock. Sorry about this super stupid noob question...

side note: the dumb company spray painted the block and there is that silver spray paint on part of the valves.... I personally am not a fan of that or is it ok and I am being way to picky??

He would need to take the bottom end apart and have the block decked for this gasket. The composite will not require this, and will hold good power.

Yup that is why i am doing the composite.

If you use ARP head studs a Felpro composite will likely hold everything you'll throw at it. My car runs a $26 Felpro composite at 30 psi tuned on 93/meth.

I'll be using that (or another brand) on my other block i will build. They are good but I need the extra money for other parts instead of getting the block decked ect

Awesome I'm glad to know that it's a good product. my brain is always like " you get what you pay for" haha but there is exceptions. Now I just have to figure out the exact limits of my stock block, yippie
