head bolts

[TangMan50]

I'm reading conflicting things about cylinder head bolts... Is it okay to reuse them or best to buy new ones? I've never heard of bolts that can only be used once......

for a hi-performace build or un-naturaly asperated motor Id get a new set of head studs. Otherwise your fine IMO, but I bump up the torque specs by 5 or 10 lbs.

i just went through the same problem. do i reuse the bolts or purchase new? the stock bolts are "torque to yeild" which means that once those bolts are torqued to spec they have been stretched to their limit and should not be reused. if you do a search on this you will find most people have had horror stories when reusing stock bolts. too many things can go wrong. so i went ahead and just paid $40 for new ARP bolts that i can use as many times as i want. i have too much money and time invested in my motor for something to go wrong because of a damn bolt. im sure your the same. just my opinion.

Does the same apply for the main cap bolts and rod bolts also?

Are you talking about these ARP bolts?

yeah
ps. studs are always a better choice than bolts

but with studs u need to raise motor... or they wont slide on. yes better... easier no

So you pull the studs out of the block. I dont see the problem. Once the studs are out. It is no different than using bolts.

somewhere around the mid 90's they used torque to yield bolts, and those must be tossed. However, on the earlier 5.0's, they weren't tty bolts and can be re used

get some arp bolts and be done with it

I agree completely, but not everyone can afford a $50+ box of bolts on the fly, that's probably why he asked this question in the first place.

IIRC...

the TTY bolts are gray... reusable bolts are black.
