Im new to building engines and notice alot of people will replace there head studs. i was wondering what purpose it is for?-

 

When you reuse head studs they can actually stretch. Therefore you have an easier chance of blowing your HG because the metal bolts stretch not clamping tight on the HG.
I picked up my ARP set for ~$100 IIRC.

 

You mean they replace their head bolts for ARP head studs.
The general Honda engines don't come with Head Studs

 

head studs shouldn't strech either

 

The reason stock "bolts" stretch is because they were designed to. TTY=Torque-to-yield

Since when did 88-01 Hondas have torque to yield head bolts?

 

are the APR head studs one time use like the OEM ones are supposed to be or are you able to torque them down more then once with the same reliability??

 

I thought they were?

::runs to garage to find old head bolts::

where the hell is ur garage...mexico?
whats the verdict

 

reuse of headbolts is fine.

extremely reputable honda dealership here don't use new ones.

I'd really only worry about replacing them if your head lifts or warps..
