[Alpines] New Head Bolts / Studs?

[jacranwell at aol.com]

Hi Walt,


The standard studs, threads, and nuts have always worked for me.


A key part of the procedure for re-installing the head is to completely clean
the stud/bolt channels, as a build-up of crud causes the bolt to bottom out on
the crud, before fully tightening down the head, even if the max torque
setting has been reached. The correct tightening sequence is also important,
as is a re-torque after 1,000 miles or so.


A great solution would be to use the single-use bolts, which use a stretch
shoulder to ensure they do not come loose, as used on most modern cars.
However, I doubt they are available in anything but metric options.


Jules.

I'm keen on replacing the 40+ year old bolts in my 1725, after blowing a
new head gasket.

I've even heard of them breaking before reaching specified  torque.

None of my usual suppliers have replacements. (SS, CS or  VB)

ARP offers fine to coarse studs, not the fine to fine thread on the  stock
motor. (will studs fit under the rocker assembly?).  Any thoughts on
torquing with a coarse thread pitch?

I'm open to solutions current,  or historic.  Nothing found in my searches.

Anyone with a box of NOS bolts? Extra studs?

Thank you,
Walt
