head bolts

[SRT_DSTRHOLC]

Can I re-use my head bolts...they have less that 300 miles on them. Took them off to change heads. Want to know if its ok and what Should i torque them to now

Head bolts have been reused for years on most motors. Just use whatever the book gives for torque value when you reinstall them.

The only thing you might want to do is chase the threads in the block if they haven`t been done yet.

 

[SRT_DSTRHOLC]

even if the motor was put together already? jw so what your saying is chase them every time I tear it apart? jw

its a 76 360, but the head bolts are Mopar ones that I bought for the magnum head conversion

oh.. reuse them..np. if your curious tho you can do the old "stretch to yield" test. that envoles measuring the
length of a brand new head bolt and compare it to a head bolt that has been torqued. there is a difference in
the length.. but no worries.. reuse them.

No, if you chased the block threads just 300 miles ago you shouldn`t have to do it again now. If you didn`t do it before though it`s a good idea because it helps to attain the proper torque readings.

reuse, I have never had a problem ever in the past 6 to 10 heads I have installed. back in the day :-D I worry more about buying junk that is not up to par these days :toothy10:

Unless they have been stretched or disfigured, they should be okay to re-use. Just remember to put them back in the right place. Short ones along the bottom, longest ones in the oil galley on each side and the others fill in the rest of the top.

You should be able to re use them
