After chasing the Holes to remove the 15+ years of crap that will prevent them screwing in hand tight of coursemkiiichip;1682661 said:
Yes, they should go all the way to the bottom of the holes. Bolts only use about half the threads while studs use them all.
You chasing threads should look something similar to this:
Note that tap in the left hand, and looking to see if all the crap got taken out...
[SUB]I've just wanted to use that pic since it was taken [/SUB]

I had to use a normal tap (also, make sure it's for blind holes, flat tip,not pointed). Broke one of the "thread restoring" taps...
I used a bottoming tap after running a chasing tap down the holes- 4 of the studs still would not thread all the way in
This worked really well to clean all the holes on my block. Soaked the holes with engine degrease overnight and then used this the next days and it was good to go. I cleaned all of them and I could of screwed all of the studs down by hand. A level on them helped to show they were equal. You will be suprised all the crap that would come out of there.

A tap and a chaser are two different things, just watch your wording. You're not sending a tap down the threads. Taps are meant to cut threads, chasers are meant to clean/repair threads. (and by repair, not something that's completely mangled)

Hence my above post a page back....
If you are confused what to use to clean the threads, buy this. Soak the holes with engine degreaser, let it sit and send this down in there and turn it back and fourth. Rinse with gas and inspect to see it is all clean.
Helps people to avoid using a tap instead of a chasing tool. I used this with that method and I was able to screw all the ARP studs in by hand ALL THE WAY DOWN.

What's so hard about buying the correct tool for the job they're NOT expensive.... :nono:
Seriously if you're going to work on a 7M chances are you'll use it again..

LOL! You said expensive was the issue? Just trying to make cleaning the threads a dummy proof job if they cannot tell the difference between a chase or a tap. :nono
Wire brush and degreaser ISN'T going to remove corrosion....
If you're going to do the job may as well get the right tool to do it properly.

How does crap get under there to begin with if the engine was never taken apart and corrosion as well?
