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!

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.

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 **** 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
