is there any type of adhesive or sealer or anything that should be used?

i only need to put one in...had it removed to repair hole from porting heads.

Nothing is needed other than some assembly oil which can help get them on. You can also do it dry.

ok, thanks...i remember seeing a pic of someones heads and it looked like something was squished out from around the guide when it went in. just wanted to clear that up.

Pressing out the old guides and installing new ones can be difficult. The guides are a tight interference fit. Cracking the head or galling the guide hole is a risk. You should preheat the heads in an oven prior to guide removal. The head should also be preheated to make it easier to install new guides, which you can also put in the freezer overnight to further ease the interference fit. You should lubricate the new guides before installing them.

I am less of a DIY'er than I used to be. More money, less time, and a greater appreciation for specialization are the reasons. Last time I knew, it cost ~$120 labor to have new guides installed in two sets of heads (16 guides). A set of (16) bronze guides should be ~$75 so the whole job would be in the ~$200 range.

That about right Rich. A set of Ferrea guides are about $90 and it's easily a 2-3 hour job all in all with the right parts so $70-$135 would be about right for the labor.

You can also pack them in dry ice and leave them overnight,and they will fall in the hole with no head heating.

Where were you when I needed you? The wife does not like engine parts in her oven

Been Rat Cheer.Did your wife say the food tasted funny.Women are funny about their kitchen.Mine says the same things.Putting powder coating in the oven is a mortal sin,I found out.Had to repent for week's.

i only have to install one. ive had it in the freezer ever since i got the head back(several months...lol!), so it should go in with no problem...

The freezer won't work,use dry ice to make it slip in by hand.Your freezer won't make it cold enough to shrink it enough.

marshall93z

where do you get dry ice?

rskrause

I "ruined" an oven powder coating

Call your ice house or some truck stops have it. Get a small cooler and line it heavy with newspaper,put some dry ice on the bottom.Put in your guide and more ice on top,break it up so there is ice all around it.Duct tape the lid shut and leave for at least 8 hours.Do not pull out untill ready to install.Make sure you have everything ready.You only have one shot to get it where you want it ,so make sure you are ready and then install.If you screw around with it it will warm up and stick in the bore and it won't be where you want it.

WARNING: HANDLE ICE WITH GLOVES AND PLIARS,AND WEAR SAFTY GLASSES.
It will burn you like a torch and put an eye out in a heartbeat,so handle with care.

EDIT:2# should be enough,it's about $1.50 a #

That's easy to do.
