I need some advice about my cylinder head change out

[9ringer]

So I have a question with regards to me taking out my old cylinder head unit and replacing with a new functional one. From my reading I am seeing that the head bolts will need to be replaced, is that because they have been stretched?

Thanks.

It is a general rule to replace them after replacement of head. But I have heard of people reusing head studs. If it were up to me I would simply buy new ones.

Dude, you do not want to be re-using head studs. You will have gasket issues if you do. The studs stretch after a while and you need to change them with the new head so that you have a tight, perfect seal.

Actually, there is a service limit on the studs. If you have access to a dial caliper you can check them to make sure they are within the service limit. I've changed out my head a lot and I've never seen the studs stretch beyond the service limit.

Yeah, think about the longitudinal stresses (stretching the bolt). Worth the slightly higher total cost (vs doing it AGAIN).

Thanks for your advise.
