Tips of the Day:

When installing the last lock ring for the pistons pins, place a rag under the piston before installing/ trying to install the lock ring.

* Best case, the rag will catch the pin when you drop it or it flys off.
* Worst Case, you forgot about the rag and the lock ring falls inside the engine case

Good news is it only took 30 mins to pull the piston /cylinder and go fishing with a magnet to get the lock ring out of the case

A big thank you to @rick1952 for the head bolt washers...
Heads are torqued and installed with the air guides on both sides

Place the paper in the lifter holes to keep debris out (or in my case dropping a cheese head screw into the engine) learned this the hard way with the piston pin retainer springs

Looking good. I used a strip of duct tape to cover the lifter holes, cheap, easy and every mechanic should always have some on hand at all times

@930cabman thanks for the tips with the duct tape or painters tape. Also for the support during the build. Getting close as I finish up the valve geometry for the two replacement push rods and checking the clearance of the 911 swivel rocker tips to rockers.

Best Regards

-Robert

I use an extra large leaf bag and bag the engine whenever I'm not working on it.

With heads on the bag is too small to bag the engine from front to back, I put it on sideways, valve cover to valve cover and it just fits a /4.
For a /6 I cut and tape up two bags together.

COLD OUT SIDE!
Cut and replace the 2 bent push rods. I scribed the OAL length and the cylinder number on each pushrod. So cutting to required length was EZ. Both intake push rod length 10.704in/27.188cm and within 0.001" of each other
Next add the push rod tubes and lifters and set up the rocker shafts...

I have been happy with the early Italian Weber 44 carbs and the Pierce manifolds... but I do have a set of 40idfs too. Cam shaft is too big for Djet. Maybe ok for LJet (I have one saved if I get tired of carbs)

Here is a a pic of the before and after with the addition under cut

After a quick clean up , they will be ready to go back in the heads and button things up with a valve lash of 0.001"-0.002" and new valve cover gaskets. This is for a little extra oil in the elephant feet as the engine breaks in again

What is your piston to valve clearance?

With the new 0.050" valve notches in the pistons I think it end up being :
Intake @ 10 degree first opening. 0.150 in min piston to valve clearance
Exhaust 10 degree before closing. 0.118 in min piston to valve clearance

Today added the push rod tubes and the rocker arms and mocked up the headers for the thermostat

Addition clearance is needed to mount a thermostat with the use of these headers. SO making a new bracket to check the clearance and function
