The 1st head is done I think....at least this part, I still need to add the oil returns and probably some new bosses for the cam cover screws to replace the ones I cut off.

It looks like I need to do a little work on the timing cover to, I guess I'll cut a section of the back out and weld in a new piece I can machine to match the head.

I got my vw heads gaskets today.....which are actually head shims, made of aluminum and not particularly useful

Back to searching.

through away the VW shims while cleaning up the bench

Dave,
Have you got a source for those?

Reusable is nice but so is compressible because it gives me a bit more tolerance on the heights.

It’s not as bad as it seems. Most of what I'm doing is really just fab work that relies on ferrari’s engineering. Also, most things interact in only 1 way with other parts, for example as long as
I get the timing chain straight it will work with the sprockets. There are a lot of parts, but it can be tackled one part at a time and it will get done and it will work.

I’m pretty confident it will work when I’m done and won’t need to come back out and back apart….we’ll see…..

I'll take another look....I remember copper rings, but they may be early engines only as was posted a bit ago.

They look way cool...any idea on price?

I hit the timing cover quickly with the die grinder so I could put it on and have a look at thinks. I’m thinking the TR cam cover would look better if I cut the side off that was the oil return on the TR…it looks like an appendage to me. I have to work on the cover any way since it needs a flange to seal to the timing cover and it need a “ferrari” script put on since it’s on top of the engine now. I’m also thinking I’m going to narrow up the timing cover a bit. The 2 changes together should make the finished engine look smaller and also help further confuse anyone who thinks they know what they’re looking at when they see it

These cams need to be cut at the seal flange and then have the flange machined to accept the timing sprocket. It looks like I'll need rework the sprocket too because there isn't enough meat on the seal flange for me to cut deep enough to get the sprocket in line. The fun just keeps coming.

I'm going to move on to the second head I guess before I go to work on the timing cover. That one is harder because it looks very much like I'll cut into the water jacket if I just mill it like I did the first head. Maybe a little off the head, and then a notch in the timing cover....I could just mill the head and weld a plate in to re-seal it, but I'd rather not do that much welding on the head if I can find another option.

TR cams, the 400 sprockets are just sitting there....the sprockets have a bore about 1mm bigger than the TR cams so they go on but flop around.

I cut the second head and rough cut the back out of the timing cover to get it on.

I’m thinking I’m going to make the 2 little top covers for the timing cover part of the cam cover for a couple reasons. 1st is then I don’t need to fix the big hole in the front of the 2nd head and 2nd because it will make it much easier to keep the width of the 2 covers the same in spite of 1 head sticking out 5mm farther than the other.

I think that’s it for today….it’s starting to at least look a bit like it could be an engine some day now.
