Head Studs won't thread in all the way...
 

Putting in my head studs, and I noticed a few on the driver's side won't thread in all the way. All of the studs on the passenger side stick out about 2.5", while a few on the driver's side stick up about 3". I can't imagine that there is anything in the threads, this block has been hot tanked and meticoulsly cleaned. So is this okay? or am I going to have to chase out the threads? Thanks!

My main studs wouldn't go all the way in... Chase the threads with a tap and put compressed air down the hole, should be golden...

I was told to not use a tap. Plus finding an M11x2.0 tap anywhere locally will be a nightmare. I'm using a ground down head bolt but it doesnt seem to be working. I think there is just a pile of junk smashed down in the very bottom of the hole. I'm trying to use a screwdriver to scrape it off the bottom.

you need compressed air

Cleaning threads
 

ARP sells a thread cleaning chaser 912-0011 for 11 mm x 2.0 pitch

Do not use a tap.

I just cut some groves in the stock bolt and use it as a chaser.

My block had a bunch of stuff in nearly all the head bolt holes. I turned the block upside down shot some brake clean in there and used compressed air to blow it out. On a couple of holes had to use a long screwdriver to break it up then breakclean and blow it out. Then used thread chaser.

Ok, I got them cleaned out. Here's what I did. I filled the holes with acetone and let it sit for 10 or so minutes to dissolve what loctite and shit was in there. Then with the acetone still in the hole I took a long sharpened flathead screwdriver and poked and twisted all of the crap off the bottom of the hole. I then blew out the holes with a compressed air nozzle with a long entension. What came out is best described as a compacted mud and sand mixture. I don't know how it got there, and frankly I don't want to know. Then I chased the threads with a grooved stock bolt followed by more compressed air. Now all of the studs are sitting at the same height

There were head studs in it when I got it and all were fine. I hope your hot tank guy dosen't have a "sand cleaning" cycle.:D

By hot tank, I meant it got done at Katech, I'd imagine. The only cleaning I did was a good old cleaning with a sponge and a hose in the driveway. Well... sponge, tube scrubbers, 5 different kinds of cleaners, and two hours :)
