On the late model 5.0 blocks, do all of the head bolt threads go into the water jackets or just the lower ones?

Thanks man, that saved me a lot of work. Now I just have to reseal the lower bolts.

i hope you arent using TTY bolts...

he means the stock bolts.TTY stands for torque to yield,which means you shouldn't use them more than once

I'm using ARP head studs. I used the regular moly-lube on the studs becuase I did not realize that that there was a difference between the bolt passages on roller 5.0 to the 289...when water started coming from around the head bolts I realized that there was a difference between the two. I have the teflon thread sealer and have been cleaning the threads out with a gun cleaning kit (and some brake cleaner)...I was asking because I wanted to see if I needed to redo all 20 studs or just the lower 5 on each side. Once again, thanks for the help,
