Stud holes in K Head
Turbo Mini Forums

Am I right in that I seem to remember someone doing the BMW K head conversion had drilled the stud holes out in the head to make it easier (no rubber mallet needed) fit ?
Been searching for days and can't find anything.

If the studs are drilled correctly and squarely in the block its not an issue surely?
Ive had my head off a few times and never had to use force to fit or remove? Rs head and ARP studs.

All drilled on a pillar drill and tapped by hand Shane, couple are not perfectly square. Head goes on ok but can't get it off without a few taps with my rubber mallet.

Might be worth trying to search for sectioned head.

John K cut one up and if your lucky one of the passes might have hit a stud hole so you can see how much material is there.

Yep already found that thread thanks bud, 3/8" clearance drill size is 9.80mm. If you look down the stud holes you can see they appear to be sleeved, this was done for a reason well you'd think it was lol.
Guess no one else remembers the thread where they open up the head stud holes in the head ?

Finally found the thread with the same problem with the studs not been square.
