[DeTomaso] Head Bolts or Studs?

I always do studs.

You can remove the heads with the studs in place.

Even if you couldn't, the current ARP studs have allen-head holes in the
top, so you can remove the studs sorta like a bolt.

Subject: [DeTomaso] Head Bolts or Studs?

     I have to decide whether I want studs or head bolts to hold my new CHI
aluminum heads to my Cleveland block.  My concern with studs was that I
thought it made it impossible to get the head off in the car,  is that
right?  Someone told me that it would be better to use the studs since I
have aluminum heads on a cast iron block and because of the different
expansion rates of the two metals,  the stud would give more to allow the
aluminum to expand?  I'm planning to use ARP fasteners.  One potential
advantage to the bolts,  is that the small headed bolts should allow
retorquing without removing the valve train.  So what do youse guys think?
