Head Bolts

[Clownfish]

My engine was rebuilt at a local machine shop but I have discovered that they did not put sealant on the threads of the head bolts. I want to add the sealant. Can I remove the bolts one at a time and reinstall them and torque them as I put them back in or do I need to remove them all and go through the proper sequence to torque them all? I will be using new head bolts. I was concerned that I might have a problem with the head gasket if I remove all of the bolts at the same time.

One bolt at a time. Torque down. When finished, recheck the torque on all head bolts.

Curious...what sealant will you be using? The Copper ? stuff? Spray or is there a brush on? Thanks, because I think the shop that did mine may have done the same thing, and I was going to also remove one at a time to coat them.

I use non hardening gasket cement. Brush on type.

I use Permatex non hardening in the tube.

I will be using one that the case dealer recommended and sold me I'll have to look at it and let you know what it is.

if you have coolant in the engine you need to drain it first. At leas partway or you will get a nice fountain.
