88 CI to 98 CI UPGRADE

Well if ya haven't getten them yet, get yourself the Snapon dog bones that are mentioned in the shop manual. Its the only way to accurately torque the rocker box and cover bolts.

The torque values they give has figured in the fact that the length of the dog bone effects the torque reading.

here are some pictures of the returned head. If you guys can tell me where the damaged occurred, I will forever think that you are a genius. BP, you don't have to worry!

I was just going thru the beginning of the thread. (I wasn't following it closely back then) I was re-discovering what you discovered before me. I should have followed your thread in the beginning. My frame isn't as wide as yours but I still had similar issues with bolts and clearances. You were very good at cataloging your project.

Now that I have my head back, I think that I am going to start getting all of the miscellaneous o rings that are going to be needed and stat installing them. I have been putting in some extra time at work so the time that I find is going to difficult for a little bit, but I will get it done. One item that I will be rebuilding so to speak is the oil pump. I have to get that put back together and of course in the right way. I do believe that this weekend I will be getting all the bolts into my little makeshift work are in my basement and start getting them all cleaned off of locktite. Once that is done, thend it really is just a matter of waiting until my heads are done and the jugs to be bored......

what happened to the head that needed repairing?

:roflmaoroving Issac Newton's theory works in Minnesota too....:roflmao:

Looks like they did a real good job JB...can't tell which fin/fins from a side view...

Yes they did. Now it is just a matter of getting the heads done.

By the way here is my Indi's shop and is also where I am getting my heads done... Just thought I would show you...

I thought that I would back track just a little bit here and point out something. Take a look at the picture below. The picture there is showing the support shafts for the rocker arms. These are installed through the support plate and then through the rocker arms. The rocker arm should not move side to side at all while the support shafts are installed. If they do, you will have to shim them to prevent them (rocker arms) from moving. Now notice the notches that are present in the support shafts? The support shafts have to be installed in such a way to where those notches are lined up with one of the bolts that fastens the support plate to the head. This holds the support shaft in place and will not allow it to move. The support shaft will only work one way.

I just thought that I would point this out for the people that may have never done this before.



Today I am going to do a few other things. I am going to head to my indy's shop and drop off the intake manifold so that can be port matched to the head and also drop off the compression releases so he has all of that for when he ready to drill. I am also going to be heading to the dealership today and getting misc. orings and start installing them where I can. (Mainly Lower end O-rings).

just wondering,what did the guy charge to fix the heads?

Well I wasn't able to get to the dealer to pick up some o-rings for the cam chest but I did get to my Indy's shop and drop off the compression releases and intake manifold. I checked the manifold there to see if it needed to stay there for port matching and it is still there. I guess that means yes. We are also going to use 80 grit aluminum oxide to give the inside of the manifold a nice texture. For those that may not know or understand the reasoning behind wanting a "rough" texture on the inside of the manifold, the reasoning is that by doing this, it allows the air fuel mix to remain suspended so the velocity takes in more of the air fuel charge. A rough texture creates more TURBULENCE. and aides in Volumetric Efficiency or (VE). A smooth surface impedes that by allowing the charge to cling to the wall of the manifold.. (This is a basic description of what it does only).

Gas going in the rough part helps atomize the gas better. Just like the intake on the heads should be rough. The exhaust should be smooth.:gah:

well,whatever it was,you should have just bought a set of `06 up heads

Got the desired headwork squared away with my indy so now it is just time to sit and wait for a little while. I will have 10.25:1 at an 85 cc head so I am having the heads cc'd, plained .020" bigger valves, intake port matched and intake ports textured, compression releases drilled and some other stuff as well. Soon the reassembly will begin. I do think that once it starts to warm up I will beging to put the bottom end back together. I am getting excited..

Northern tool has a new heater that will work on Kerosene or diesel fuel that puts out plenty of heat. Will run you out of a garage.
Buddy down the street got one.

I run a relatively inexpensive heater that mounts onto a propane bottle. Works fine for me.
