Head Bolts Question
I suspect that I have sticking or damaged valves on my 95 7.3PSD and I plan on changing the cylinder heads ....... My question is why is it nescessary to change the headbolts?... why cant they be reused, what kind of problems are likely to develop if I reuse the bolts?.... also if I have to change them where can I get the best deal on a new set?.... I dont want to get studs because I have no intention on pulling the engine.... ARP bolts sell for about 140 bucks a set and everybody recommend them.... But can I get something at a better price? I really dont want to dish out so much money on my old truck... Help!

I have never done head studs on a psd so I am not really sure.......I know on gassers once torqued they stretch....so basically if reused you would stretch it even more hence weakening the stud.I have always replace them on all my gassers once head is removed.

bolts will stretch, its a no no to reuse them. If your pulling the heads off do your self a favor and just pull the engine. It will make the job MUCH easier to do, nothing worse than laying across an engine all day. Not to mention setting down the head onto the block w/o screwing up the headgasket. The heads are very heavy.....

tim is right. it can be done one at a time. I have never done it in the truck, tranny was out so i just pulled engine and did studs one at a time. If you do studs in truck, you'll have to jack the cab or cut hole in firewall for socket. IMO its much easier to just pull the damn engine. afterall with the proper equipment a guy can have the engine hanging in under 4 hrs. ive done it in just under 3 hrs before....

X2 on bolts stretching. If one should break while your torquing it down that in its self will ruin your day. It's just not worth the chance.
On KLR650 Duel sports when you pull the fly wheel it is always recommended to buy a new bolt ($12.00) Torque is around 150-180# don't recall exactly. Many guys don't and have problems. I know of one that broke, had to pull the engine and take it to a machine shop to get it removed, Cost? Don't know but I'll bet it was more than $12.00.
